A lawn maintenance device that is calibrated in the field by a user through a mobile software app to irrigate and/or fertigate one or more arbitrary geometrical areas defined by the user. The device includes a motorized rotary drive mechanism for controlling the rotational angle of a pivotable nozzle and a flow control valve for controlling water jet throw distance. At least one container is integrated into the device for dispensing fertilizer, herbicide and other such concentrated lawn or garden solutions. The device communicates with and is controlled by a web server which dynamically computes a watering path and triggers the device to commence irrigation over the computed path based on prevailing local environmental conditions and/or user settings.

A reservoir dispenser for a bidet washing apparatus includes a housing unit having at least one chamber, wherein the at least one chamber is capable of holding a liquid wash solution; a water inlet, a connecting tube, and a water outlet, wherein the water inlet, connecting tube and water outlet are in fluid communication, wherein the connecting tube is located between the water inlet and the water outlet, wherein the connecting tube includes a choke, and wherein the water inlet, connecting tube, and the water outlet are connectable to the housing unit; and a suction tube located between and in fluid communication with the at least one chamber and the choke.

A dispensing system (2000), includes a container (900) containing a flowable base formulation (910) to be dispensed, an additive mixing device (2004), and an actuable pump engine (2002) which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body (2022) with an internal cavity (2052), an additive ingredient (2054) within the cavity, and a flow path/mixing chamber (2058) between an input and an output. With each pump of the device (2004) the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices (2004) may be interchangeable for different formulations, and the mixing devices may be refillable.

A mix on exit sprayer having a water tank and a body the includes a chemical cartridge receiving cavity. A pump move water from the tank to a mixing chamber and a piston drives chemical concentrate from the cartridge into the mixing chamber. A venturi style mixing element mixes the water and concentrate and the pump moves the mixed fluid from the mixing chamber to a spray wand from which it can be expelled.

A spray gun includes a casing, a cup, a spray nozzle, and a pump. The pump is provided in the casing and has a spray chamber in communication with the cup. The cup includes a cup housing and a flexible cup body provided in the cup housing. A venting structure communicating the cup with an outer environment is provided on the pump. The cup housing is provided with a hollow portion, such that the flexible cup body is manually squeezable to expel air inside the flexible cup body out via the venting structure.

A hot lather dispenser includes a compartment configured to receive a removable pod, a pump configured to receive liquid from the removeable pod during operation, a heater configured to head the liquid, an auger configured to combine the liquid with air to generate lather, and a nozzle configured to dispense the lather to a user.

An exemplary tabletop foam sanitizer dispenser includes a bottle comprising a reservoir for containing liquid sanitizer. The bottle has a base for sitting on a surface. The base has a base diameter. The bottle has a top and a neck located proximate the top having an opening. The opening has an inner neck diameter. The base diameter is at least 3 times the inner neck diameter. A pump assembly is also included. The pump assembly has a cylindrical housing. The cylindrical housing having an outer housing diameter. The outer housing diameter is less than the inner neck diameter. The cylindrical housing is inserted into the bottle through the neck opening. A pump is located in the cylindrical housing. The pump includes a liquid inlet, an air inlet, a liquid outlet and an air outlet. A pump is motor located in the cylindrical housing. A battery is also located in the cylindrical housing. A nozzle housing is located above the cylindrical housing. A liquid and air mixing chamber located in the outlet nozzle housing. The liquid and air mixing chamber is in fluid communication with the liquid outlet and the air outlet. An outlet nozzle is in fluid communication with the mixing chamber and is located in a lower portion of the nozzle housing. The table top dispenser further includes a sensor for detecting a hand of a user positioned below the nozzle.

The present disclosure provides an atomization device, an aroma diffusion instrument, and an operation method. The atomization device includes an atomization chamber, a mixing chamber, a container, a repair cavity, a suction pump, and a gas pump; the atomization chamber is communicated with the mixing chamber through an atomization port; the suction pump is communicated with the container and the mixing chamber; the suction pump is used for pumping a substance in the container to the mixing chamber or pumping a substance in the mixing chamber back to the container; impurities in the mixing chamber can also be discharged from an opening of the repair cavity; the gas pump is connected with the mixing chamber to convey high-pressure gas to the mixing chamber; the high-pressure gas is used for atomizing liquid of the mixing chamber towards the atomization chamber; and the atomization chamber is provided with a mist outlet.
