Description

TECHNICAL FIELD

[0002] With the increasing demand for non-contact cleaning environment, the demand for inductive kitchen and bath equipment is increasing. The setting of inductive equipment not only solves the cleaning problem of cleaning equipment such as faucet and liquid outlet device, but also enables the equipment to be walked away after use, thereby improving the convenience of equipment use.

[0003] Among them, the inductive soap liquid outlet device is a non-contact cleaning device that uses infrared detection equipment to trigger the pump body to work and extract soap liquid. Some soap liquid outlet devices also have the function of outputting foam by mixing gas with soap liquid.

[0004] However, since the foam type soap liquid outlet device outputs foam, it needs to continuously supply air to the pump body. The current pump body uses a method of leaving a gap on the shell to enable the pump body to receive air entering from the gap of the electronic cavity shell. After the soap liquid in the liquid bottle is extracted, air needs to be provided from the shell due to the integration of the shell to maintain the air pressure balance in the liquid bottle. This setting will cause the non-sealed structure of the liquid outlet device shell to be not waterproof, which is easy to cause liquid leakage. Long-term use can easily cause the metal parts inside the shell to rust, affecting the power supply or normal work of the equipment. Even the sewage or rusty structure enters the mixed air or soap liquid output pipeline, which pollutes the soap liquid. SUMMARY

[0032] In order to describe the technical content, structural features, purposes and effects of the technical scheme in detail, the following will be described in detail in combination with specific embodiments and the accompanying drawings.

[0033] Please refer to Figures 1 to 3 The embodiment discloses a liquid bottle air pressure balance type liquid outlet device, which comprises an electronic cavity 10, an assembly port 20, a liquid bottle 30 and an air channel 40. The electronic cavity 10 is internally provided with a liquid pump 11, and the electronic cavity 10 is provided with a liquid outlet 16. The liquid pump 11 is provided with a liquid outlet end, a liquid inlet end and an air inlet 12, the liquid outlet end of the liquid pump 11 is connected with the liquid outlet 16 of the electronic cavity 10 through a pipeline, and the liquid inlet end of the liquid pump 11 is connected with the liquid bottle 30 through a pipeline and an interface. The assembly port 20 is arranged on the cavity wall of the electronic cavity 10, and the air inlet 12 of the liquid pump 11 is connected with the cavity wall of the electronic cavity 10 on the inner side of the assembly port 20 through a pipeline. The liquid bottle 30 is detachably connected with the assembly port 20. The air channel 40 is arranged between the assembly port 20 and the liquid bottle 30 of the electronic cavity 10, one end of the air channel 40 is connected with the air inlet 12 of the liquid pump 11, and the other end of the air channel 40 is arranged on the outer side of the liquid bottle 30.

[0034] According to the above structure, in the use process of the liquid bottle air pressure balance type liquid outlet device, the user assembles the liquid bottle on the assembly opening of the electronic cavity, and forms an air channel between the liquid bottle and the side wall of the electronic cavity and the liquid bottle. The air channel is communicated to the outside of the liquid bottle through the gap reserved between the liquid bottle and the shell and the assembly opening. The operator triggers the liquid pump to work through the induction window, and the liquid pump extracts the hand sanitizer in the liquid bottle, and extracts air from the area outside the liquid bottle through the air inlet, and then mixes with the hand sanitizer to generate bubbles, and then the bubbles are transported from the liquid outlet end of the liquid pump to the liquid outlet of the electronic cavity for foam output. By concentrating the air inlet area of the shell to the position of the assembly opening through the gaps of the shell, when the liquid bottle is docked with the assembly opening, the air channel between the liquid bottle and the shell provides air for the liquid bottle and the liquid pump, instead of directly connecting the liquid bottle to the electronic cavity to balance the air pressure in the liquid bottle and the electronic cavity, so that the electronic cavity and the liquid bottle rely on the air channel to provide air and maintain air pressure balance, ensure normal bubble output, the appearance of the shell is not damaged, at the same time, the electronic cavity is sealed to prevent liquid leakage, and the air inlet between the assembly opening of the electronic cavity and the liquid bottle avoids the problem that sewage is extracted and mixed during use, avoids liquid residue in the electronic cavity causing equipment corrosion, and ensures that the soap liquid is not contaminated.

[0035] Please refer to Figure 1 In some preferred embodiments, the inner side of the assembly opening 20 is provided with a liquid bottle clamping piece 21, which includes a positioning slope 22 and a guide slope 23.

In the use process, when the clamping protrusion 31 of the liquid bottle needs to be assembled into the assembly opening, it is in contact with the guide slope in advance, or directly inserted into the space between the guide slope and the positioning slope, and then the liquid bottle is rotated to make the clamping protrusion clamped into the positioning slope, and the fixing is completed. When disassembling, the liquid bottle is rotated towards the guide slope, the clamping protrusion is separated from the positioning slope, and is in contact with the bottom surface of the guide slope, which faces the opening direction of the assembly opening. During the rotation process, the clamping protrusion is pushed to the opening direction of the assembly opening by the guide slope, which gradually approaches the inclined edge of the opening direction of the assembly opening, and the guide slope provides a stroke for pushing out the liquid bottle, which facilitates the extension of the bottom of the liquid bottle when the electronic cavity is provided with a cylindrical protection structure, and facilitates the assembly and disassembly of the liquid bottle.

[0036] Please refer to Figure 2 In some preferred embodiments, the electronic cavity 10 further includes an induction window 13, which is electrically connected with the liquid pump 11.

[0038] In some preferred embodiments, the air inlet is directed to the top of the bottle body of the liquid bottle interface. By directing the air inlet to the top of the bottle body at the interface between the liquid bottle and the assembly port, the liquid dispenser is facilitated to extract air from the outside of the interface between the bottle body and the assembly port, thereby further reducing the influence on the air pressure in the liquid bottle and the electronic cavity of the device.

[0044] In some preferred embodiments, the number of positioning and guiding bevels arranged on the inner side of the assembly opening can be four, and they are arranged at equal intervals. By arranging four pieces, only a rotation in the range of 45 degrees to 90 degrees is required during the process of taking out or assembling the liquid bottle into the assembly opening, so that the liquid bottle can be disassembled.
