Description

Foam watering can

Technical Field

The present invention relates to a foam watering can, and more particularly, to a foam watering can that can generate a large amount of foam.

Background

The watering can is a common spraying device with high practicability, and is widely applied to different places such as families, units, schools and the like due to the characteristics of small size, small occupied area, convenience in carrying, handheld operation and the like. The watering can is commonly used in the scenes of cleaning and washing objects, such as air humidification, water spraying for plant watering, spraying of disinfectant and cleaning solution, and the like. When the object is cleaned, the liquid sprayed by the spray can contains certain cleaning agent or disinfectant, and the liquid can generate certain amount of foam, so that the spray can is used as a foam spray can.

In cleaning and washing of objects, such as automobile cleaning, glass cleaning and the like, the liquid sprayed by the foam spraying pot is required to have rich foam, and the use and the operation are simple and convenient. The existing foam watering can is usually packed with a dense sponge in the nozzle part, and the sponge is provided with pores to allow the liquid to pass through the sponge to be mixed with water and air so as to generate abundant foam. After a long time of use, the sponge can absorb impurities in the liquid to block part of the pores in the sponge. Also, in order to generate a large amount of foam, a more dense sponge needs to be packed in the nozzle. However, to pass the liquid through the dense sponge, the pressure of the water injection, i.e., the pressure in the foam spraying pot, needs to be increased. Common designs increase the pressure in the foam watering can by injecting gas at high pressure into the foam watering can, but this can create a safety hazard to its use and is inconvenient to use.

Furthermore, although the existing foam spraying pot has a way of injecting gas into the pot to obtain abundant foam, it needs to use a large amount of detergent and is not environment-friendly.

Accordingly, it is a primary object of the present invention to solve the above problems by providing a foamer which does not require high pressure insufflation and which can produce a rich foam with less detergent.

For ease of understanding, the illustration of the embodiment of the foam watering can in this case is illustrated by way of example with a hand-held foam watering can 1. Referring to fig. 1 and 2, fig. 1 is an overall view of a hand-held foamer can according to the utility model, and fig. 2 is an exploded view of the hand-held foamer can shown in fig. 1. To achieve at least one of the advantages described above or other advantages, one embodiment of the present invention provides a hand-held foam spray can 1 including a motor pump 10, a foam tube 12, and a nozzle 14. The motor pump 10 is used to draw in air and solution and pump out the liquid-gas mixture. One end of the foam tube 12 is connected to the motor pump 10 for transferring the liquid-gas mixture pumped by the motor pump 10 and mixing the air and the solution sufficiently to generate foam. The other end of the foam tube 12 is connected to a nozzle 14, and foam is discharged through the nozzle 14. Wherein the length of the foaming tube 12 is between 10cm and 500cm, the inner diameter of the tube is between 0.8mm and 20mm, and the pressure of the liquid-gas mixture in the foaming tube is between 8 PSI and 32 PSI. This arrangement provides sufficient mixing of the air and the solution in the foaming tube 12 for sufficient time, space and liquid-gas mixing conditions to allow for the ejection of a rich foam from the nozzle 14.

In one embodiment, the ratio of the air to the solution in the liquid-gas mixture is between 1:1 and 10: 1. This hand-held type foam watering can 1 can be used to general common washing occasion, like car wash, glass cleanness etc. between this gas-liquid mixture proportion, the mixing uniformity and mobility, the foaming multiple of this liquid-gas mixture are in and use required preferred state, can produce abundant, have the foam of certain fineness concurrently, and then ensure the cleanness or the cleaning performance of different demands.

Referring to fig. 3 in conjunction with fig. 2, fig. 3 is a schematic diagram of the motor pump and piping in the hand-held foam sprayer of fig. 2. In the illustrated embodiment, the hand-held foam sprayer 1 further includes a first conduit 16 for delivering air to the motor pump 10; and a second pipe 18 for feeding the solution into the motor pump 10. The first pipe 16 and the second pipe 18 are used to input air and solution into the motor pump 10, so as to effectively control the injection amount of air and the input amount and speed of solution, and further precisely control the gas-liquid mixing ratio of the liquid-gas mixture.

In one embodiment, the hand-held foam sprayer 1 further comprises a regulating valve 19 connected between the first pipe 16 and the motor pump 10 for regulating the amount of air injected into the motor pump 10 from the first pipe 16. In other words, the injection amount of the air in the first pipe 16 to the motor pump 10 is controlled by the control valve 19 to further control the gas-liquid mixing ratio of the gas-liquid mixture, thereby controlling the quality of the foam sprayed from the nozzle 14 of the hand-held foam spraying pot 1.

In one embodiment, the hand-held foam sprayer 1 further comprises a check valve 11 disposed between the first pipe 16 and the motor pump 10 for preventing the solution from flowing back through the first pipe 16 when the hand-held foam sprayer 1 is poured.

In another embodiment, the hand-held foam sprayer 1 further includes a filter (not shown) disposed between the first pipe 16 and the motor pump 10 for filtering the air injected into the motor pump 10 from the first pipe 16. The filter screen can prevent impurities carried in the air from entering the foaming tube 12 to block the foaming tube 12, and further affect the mixing effect or foaming effect of the liquid-gas mixture in the foaming tube 12.

In the embodiment of fig. 1 and 2, the hand-held foam watering can 1 can comprise a can body 20 and a lid 30. Wherein the kettle body 20 is used for containing the solution, and the cover body 30 is used for containing the motor pump 10, the foaming tube 12, the first pipeline 16 and the second pipeline 18. The can body 20 and the cover 30 are connected and fixed by screwing, but not limited thereto, and can be connected by buckling and locking, and the two can be connected and fixed and sealed.

One end of the second pipe 18 is connected to the motor pump 10, and the other end extends into the kettle body 20 to pump the solution. The solution includes water and a cleaning agent. The ratio of water to detergent in the solution is between 1000:1 and 1: 1. The volume of the kettle body 20 in the handheld foam watering can 1-2.5 liters (1000-2500 milliliters). For example, when the amount of water in the solution is 1000 ml, only 5 ml of detergent is mixed with the water and a rich foam is ejected from the nozzle 14 through the foaming tube 12. Compared with the existing foam watering can, the use amount of the cleaning agent can be saved, and a better foaming effect can be achieved. Referring again to FIG. 2, the end of the second conduit 18 extending into the kettle body 20 is connected at its end to a filter 180 for filtering the solution in the kettle body 20. Thus, when different kinds of the solution or the cleaning agent are mixed in the kettle body 20, the foaming effect of the liquid-gas mixture in the foaming tube 12, such as the foaming amount and the density of the foam, can be further improved. Depending on the type of solution, different filters 180 may be used. In the example of fig. 2, filter 180 is a screen.

Referring to fig. 2, 3 and 4, in the embodiment shown, the regulating valve 19 is located at one side of the motor pump 10 and connected to the first pipe 16 (input air) located above the motor pump 10. A knob 40 is provided above the housing of the cover 30 for controlling the regulating valve 19. The adjusting valve 19 and the knob 40 can be connected in a thread screwing manner. The check valve 11 is disposed between the first pipe 16 and the motor pump 10 and at one end of the first pipe 16 near the regulating valve 19. The second pipe 18 and the regulating valve 19 are located on the same side of the motor pump 10, and draw the solution from the kettle 20 and input the solution into the motor pump 10. After the air input from the first pipe 16 is mixed with the solution input from the second pipe 18 through a three-way joint 17, the liquid-gas mixture is input into the motor pump 10 through a third pipe 22. The motor pump 10 is connected to the foaming tube 12 through a fourth pipe 24, and pumps the liquid-gas mixture into the foaming tube 12 (as shown by the arrow in fig. 3) for mixing and foaming, and then discharges the foam from the nozzle 14. The foam tube 12 is disposed inside the housing of the cover 30 in a spiral manner. When different detergents are adopted, the adjustment of air inflow can change or adjust the density of the foam. The more air, the more dense the foam, the longer the surface remains for cleaning, the better the cleaning power, and the less relative detergent is used.

In one embodiment, the pipes are located above the motor pump 10, and the foam tube 12 can be arranged above the motor pump 10 in a manner of circling around the pipes, and further arranged inside the casing of the cover 30. The foaming tube 12 has a certain flexibility, so that the coiling is convenient, and the bending is prevented from affecting the conveying of the liquid-gas mixed liquid through the coiling mode, or the mixing effect and the foaming effect in the foaming tube 12 are reduced. The foam tube 12 is disposed in such a manner that the space for accommodating the foam tube can be saved and the space in the lid body 30 can be fully utilized.

As shown, the cover 30 may further include an upper cover 32 and a lower cover 34, and the upper cover 32 and the lower cover 34 may be connected by a snap-fit manner. The lower cover 34 has a hollow cavity with a receptacle 36 for receiving the motor pump 10. The motor pump 10, the regulator valve 19, and the pipes can be mounted in the socket 36. Therefore, the components are compactly and orderly arranged in the hollow cavity of the lower cover 34, so as to fully utilize the space of the cover body 30. The socket 36 is connected to the nozzle 14 by a connector 360. The socket 36 and nozzle are shown as being threadably secured together. One end of the foaming tube 12 passes through the connector 360 and then communicates with the nozzle 14.

The lid 30 has a handle 38, and the hand-held foam watering can 1 can be held by a user via the handle 38. The handle 38 may be provided with a stripe shape to increase friction force and prevent a user from slipping when using the hand-held foam watering can 1. A battery 380 is provided within the handle 38 for providing power to the motor pump 10. The battery 380 is electrically connected to the motor pump 10. In the illustrated example, the battery 380 is connected to the motor pump 10 via a wire. The battery 380 may be a conventional disposable battery, such as a No. 7 battery, a No. 5 battery, or the like. The battery 380 may also be a rechargeable battery, and the cover 30 has a charging hole for charging the battery 380. In the example of fig. 1, the charging hole in the upper lid 32 is covered by a waterproof plug 50, which protects the charging hole from water when charging is not required. When the battery 380 needs to be charged, the waterproof plug 50 is pulled out. One end of the waterproof plug 50 may be fixed to the cover 30 to prevent loss. But is not limited thereto. The waterproof plug 50 may be provided separately from the cover 30.

In one embodiment, the cover 30 has a touch switch 60 located on the upper side of the handle 38 for controlling the switching of the motor pump 10. Further, the touch switch 60 is located on one side of the upper cover 32, and the knob 40 is located on the other side of the upper cover 32.

In summary, the present invention provides a foam spraying pot, which can spray abundant foam through a nozzle after air and solution sucked by a motor pump are fully mixed by a foaming tube, and high-pressure air injection is not required. In particular, the present invention can produce as much foam as a conventional foam can by using approximately one-tenth of the detergent. The more air, the more dense the foam, the longer the surface remains for cleaning, the better the cleaning power, and the less relative detergent is used. Meanwhile, the handheld foam watering can provided by the utility model is simpler and more compact in structure and convenient to carry and use.
