Description

Foam spray bottle and quick-release structure for foam spray bottle

The present invention relates to the technical field of foam spray bottles, in particular to a foam spray bottle and a quick-release structure for the foam spray bottle.

A spray can is a common and practical spraying device. It is widely used in different places such as homes, units, and schools because of its small size, small footprint, easy portability, and handheld operation. Spray cans are often used in air humidification, watering plants, and spraying disinfectants and cleaning liquids to clean and wash objects. When cleaning and washing objects (such as vehicles), the liquid sprayed from the spray can contains a certain amount of detergent or disinfectant, and the liquid will produce a certain amount of foam. At this time, the spray can acts as a foam spray can.

In the cleaning and washing of objects, such as car washing and glass cleaning, the liquid sprayed from the foam sprayer is required to have relatively rich foam and be easy to use. Existing foam sprayers usually increase the internal pressure of the foam sprayer by injecting air into the foam sprayer at high pressure, so that the liquid can move upward and finally foam through the mouth to produce rich foam. In this process, there are extremely high requirements for the air tightness of the entire foam sprayer, otherwise a large amount of foam cannot be produced. Due to the high air tightness requirements, the disassembly and assembly of the entire foam sprayer is therefore very cumbersome (usually a threaded connection is adopted, which requires a large number of turns of screwing). Workers will spend a lot of working time when replacing the liquid, which is quite inconvenient to use. In addition, when foam sprayers use other methods to produce rich foam, they are also limited to the airtightness requirements of industry products and cannot meet the needs of workers.

Therefore, the main purpose of the present invention is to provide a foam spray bottle and a quick-release structure for the foam spray bottle to solve the above problems.

The purpose of the present invention is to provide a foam spray bottle and a quick-disassembly structure for the foam spray bottle, which can quickly disassemble the bottle body and the cover body to replace the solution and perform other work, thereby saving workers' working time, improving work efficiency, and enhancing the user experience.

To achieve at least one of the above advantages or other advantages, an embodiment of the present invention provides a foam spray bottle, which includes a motor pump, a foaming tube, a bottle body, a cover body and a quick-release structure.

One end of the foaming tube is connected to the motor pump, and the motor pump mixes the inhaled air with the solution into a liquid-gas mixture and pumps it into the foaming tube to generate foam. The pot body is used to contain the solution. The cover body is used to cover the opening of the pot body, and the cover body contains the motor pump and the foaming tube. The quick-release structure includes a first clamping structure and a second clamping structure, the first clamping structure is arranged on the cover body, and the second clamping structure is arranged on the pot body. The first clamping structure can be clamped with the second clamping structure along a first direction, and can be disengaged from the clamping state with the second clamping structure along a second direction opposite to the first direction at a travel distance less than half of the circumference of the pot body opening.

In some embodiments, the upper edge of the first locking rib has a first positioning structure, and the lower edge of the second locking rib has a second positioning structure corresponding to the first positioning structure. When the first positioning structure contacts the second positioning structure, the first locking rib and the second locking rib are positioned.

In order to achieve at least one of the above advantages or other advantages, another embodiment of the present invention further proposes a quick-release structure for a foam sprayer, wherein the foam sprayer comprises a motor pump, a foaming tube, a tank body, and a cover body, wherein the tank body is used to contain a solution, and the cover body is used to cover the opening of the tank body and contain the motor pump and the foaming tube, and the foaming tube is connected to the motor pump and mixes the air sucked by the motor pump with the solution into a liquid-gas mixture and generates foam, and the quick-release structure comprises a first clamping structure and a second clamping structure.

The first engaging structure is arranged on the lid. The second engaging structure is arranged on the pot body. The first engaging structure can engage with the second engaging structure along a first direction, and the first engaging structure can disengage from the engaging state with the second engaging structure along a second direction opposite to the first direction at a travel distance less than half of the circumference of the pot body opening. When the first engaging structure engages with the second engaging structure, air outside the pot body can still flow into the interior of the pot body.

In some embodiments, the upper edge of the first locking rib has a first positioning structure, and the lower edge of the second locking rib has a second positioning structure corresponding to the first positioning structure. When the first positioning structure contacts the second positioning structure, the first locking rib and the second locking rib are positioned.

Therefore, by using the foam spray bottle and the quick-release structure for the foam spray bottle provided by the present invention, the foam spray bottle can be quickly disassembled and assembled between the bottle body and the cover body through the setting of the quick-release structure, which is convenient for replacing the solution and other work, saving the workers' working time, improving work efficiency, and enhancing the user experience.

Please refer to Figures 1 and 2. Figure 1 is a three-dimensional schematic diagram of a foam sprayer of an embodiment 1 of the present invention, and Figure 2 is an exploded schematic diagram of the foam sprayer 1 shown in Figure 1. In order to achieve at least one of the above advantages or other advantages, an embodiment of the present invention proposes a foam sprayer 1. The foam sprayer 1 may include a motor pump 10, a foaming tube 12 and a nozzle 14. The motor pump 10 can be used to inhale air and solution and pump out a liquid-gas mixture. One end of the foaming tube 12 is connected to the motor pump 10 to transmit the liquid-gas mixture pumped out by the motor pump 10 and to fully mix the air and the solution to produce foam. The other end of the foaming tube 12 is connected to the nozzle 14, and foam is sprayed through the nozzle 14. The length of the foaming tube 12 is between 10 cm and 500 cm, the inner diameter of the tube is between 0.8 mm and 20 mm, and the pressure of the liquid-gas mixture in the foaming tube is between 8 and 32 PSI. This configuration provides sufficient time, space and liquid-gas mixing conditions for the air and the solution to be fully mixed in the foaming tube 12, so that rich foam is sprayed from the nozzle 14.

In a specific implementation, the ratio of the air to the solution in the liquid-gas mixture is between 1:1 and 10:1. The foam sprayer 1 can be used in common cleaning occasions, such as car washing, glass cleaning, etc. Within this gas-liquid mixing ratio, the mixing uniformity, fluidity, and foaming multiple of the liquid-gas mixture are in a better state required for use, and can generate rich foam with a certain degree of fineness, thereby ensuring the cleaning or washing effects required by different requirements.

Refer to FIG. 3 in conjunction with FIG. 2 , which is a three-dimensional schematic diagram of the motor pump 10 and the pipeline in the foam sprayer 1 shown in FIG. 2 . In the embodiment shown in the figure, the foam sprayer 1 may further include a first pipe 16 for inputting air into the motor pump 10; and a second pipe 18 for inputting solution into the motor pump 10. By inputting air and solution into the motor pump 10 through the first pipe 16 and the second pipe 18 respectively, the injection amount of air and the input amount and speed of solution can be effectively controlled, which helps to further accurately control the gas-liquid mixing ratio of the liquid-gas mixture.

In one embodiment, the foam sprayer 1 may further include a regulating valve 19. The regulating valve 19 is connected between the first pipe 16 and the motor pump 10 to adjust the amount of air injected from the first pipe 16 into the motor pump 10. In other words, the amount of air injected from the first pipe 16 into the motor pump 10 is regulated by the regulating valve 19 to further regulate the gas-liquid mixing ratio of the liquid-gas mixture, thereby regulating the quality of the foam sprayed by the nozzle 14 of the foam sprayer 1.

In one embodiment, the foam spray bottle 1 may further include a one-way valve 11 disposed between the first pipe 16 and the motor pump 10 to prevent the solution from flowing back out of the first pipe 16 when the foam spray bottle 1 is tilted.

In another embodiment, the foam sprayer 1 may further include a filter (not shown). The filter is disposed between the first pipe 16 and the motor pump 10 to filter the air injected from the first pipe 16 into the motor pump 10. The filter can prevent impurities carried in the air from entering the foaming tube 12 and blocking the foaming tube 12, thereby affecting the mixing effect or foaming effect of the liquid-gas mixture in the foaming tube 12.

As shown in the embodiment of FIG. 1 and FIG. 2 , the foam spray pot 1 may include a pot body 20 and a cover body 30 . The pot body 20 is used to contain the solution, and the cover body 30 is used to contain the motor pump 10 , the foaming tube 12 , the first pipe 16 and the second pipe 18 .

One end of the second pipe 18 is connected to the motor pump 10, and the other end extends into the tank body 20 to extract the solution. The solution includes water and a detergent. The ratio of water to detergent in the solution is between 1000:1 and 1:1. The capacity of the tank body 20 in the foam sprayer 1 is 1 to 2.5 liters (1000 to 2500 milliliters). For example, when the water in the solution is 1000 milliliters, only 5 milliliters of detergent is needed to mix with water to spray rich foam from the nozzle 14 through the foaming tube 12. Compared with the existing foam sprayer, the amount of detergent used can be saved and a better foaming effect can be achieved. Please refer to FIG. 2 again. The end of the second pipe 18 extending into the tank 20 is connected to a filter 180 at its end to filter the solution in the tank 20. In this way, when different types of solutions or cleaning agents are mixed in the tank 20, the foaming effect of the liquid-gas mixture in the foaming tube 12 can be further improved, such as the size of the foaming amount, the density of the foam, etc. Different filters 180 can be used according to different types of the solution. In the example of FIG. 2, the filter 180 is a filter.

Referring to Fig. 2, Fig. 3 and Fig. 4, in the illustrated embodiment, the regulating valve 19 is located on one side of the motor pump 10 and is connected to the first pipe 16 (input air) located above the motor pump 10. A knob 40 is provided above the outer shell of the cover 30 for controlling the regulating valve 19. The regulating valve 19 and the knob 40 can be connected by screw thread engagement. The check valve 11 is provided between the first pipe 16 and the motor pump 10 and at one end of the first pipe 16 close to 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 the second pipe 18 extracts the solution from the kettle 20 and inputs it into the motor pump 10. After the air inputted from the first pipe 16 and the solution inputted from the second pipe 18 are mixed through a three-way joint 17, the liquid-gas mixture is inputted into the motor pump 10 through a third pipe 22. The motor pump 10 is connected to the foaming pipe 12 through a fourth pipe 24, and the liquid-gas mixture is pumped into the foaming pipe 12 (as shown by the arrow in FIG. 3 ) for mixing and foaming, and then the foam is sprayed from the nozzle 14. The foaming pipe 12 is arranged on the inner side of the shell of the cover 30 in a spiral manner. When different cleaning agents are used, the density of the foam can be changed or adjusted by adjusting the air intake. The more air there is, the denser the foam is, the longer it stays on the cleaning surface, the better the cleaning power is, and the use of the cleaning agent will be relatively less.

In one embodiment, the pipes are located above the motor pump 10, and the foaming tube 12 can be arranged above the motor pump 10 in a manner of winding around the pipes, and then arranged inside the shell of the cover 30. The foaming tube 12 has a certain flexibility to facilitate winding, and the winding method avoids bending to affect the delivery of the liquid-gas mixture or even reduce the mixing effect and foaming effect in the foaming tube 12. The foaming tube 12 is arranged in this way and can save its storage space and make full use of the space in the cover 30.

As shown in the figure, the cover body 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 in a snap-locking manner. The lower cover 34 has a hollow cavity, and the cavity has a receiving seat 36 for accommodating the motor pump 10. The motor pump 10, the regulating valve 19 and the pipes may be installed in the receiving seat 36. In this way, the components are compactly and orderly arranged in the hollow cavity of the lower cover 34 to fully utilize the space of the cover body 30. The receiving seat 36 is connected to the nozzle 14 through a connecting member 360. In the figure, the receiving seat 36 and the nozzle can be connected and fixed in a threaded manner. One end of the foaming tube 12 passes through the connecting piece 360 and is connected to the nozzle 14 .

The cover 30 has a handle 38, and the user can hold the foam sprayer 1 through the handle 38. The handle 38 can be provided with stripes to increase friction and prevent the user from slipping when using the foam sprayer 1. A battery 380 is provided inside the handle 38 to provide power to the motor pump 10. The battery 380 is electrically connected to the motor pump 10. In the example shown in the figure, the battery 380 is connected to the motor pump 10 via a wire. The battery 380 can be a common disposable battery, such as a No. 7 battery, a No. 5 battery, etc. The battery 380 can also be a rechargeable battery, and a charging hole is provided on the cover 30 to charge the battery 380. In the example of Figure 1, the charging hole located on the upper cover 32 is covered by a waterproof plug 50 to provide waterproof protection for the charging hole when charging is not required. When the battery 380 needs to be charged, the waterproof plug 50 can be pulled out. One end of the waterproof plug 50 can be fixed on the cover body 30 to prevent loss. However, this is not limited to the present invention. The waterproof plug 50 can also be separated from the cover body 30. In a specific embodiment, the cover body 30 has a touch switch 60, which is located on the upper side of the handle 38 and is used to control the switch of the motor pump 10. Furthermore, 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.

The tank body 20 of the foam sprayer 1 is filled with a solution when in use, and the motor pump 10, the foaming tube 12, the first pipe 16, the second pipe 18 and other components are also built in the cover 30. That is to say, the tank body 20 and the cover 30 both have considerable weight. If the two are connected and fixed by screw thread, although the connection, fixation and sealing can be achieved, it will take a lot of time to connect or disassemble the two, and it is inconvenient to disassemble and assemble, and the rotation operation will be inconvenient due to the weight of the two. As shown in Figures 5 and 6, in some embodiments, the foam sprayer 1 may also include a quick-release structure 70. The quick-release structure 70 includes a first snap-fit structure 71 and a second snap-fit structure 72. The first snap-fit structure 71 is arranged on the cover 30, and the second snap-fit structure 72 is arranged on the tank body 20. The first engaging structure 71 can engage with the second engaging structure 72 along the first direction, and the first engaging structure 71 can disengage from the engaging state with the second engaging structure 72 along the second direction at a travel distance less than half the circumference of the opening of the tank body 20. In other words, the first engaging structure 71 and the second engaging structure 72 can be engaged or disengaged by rotating half a circle at most. The first direction is opposite to the second direction, for example, the first direction can be clockwise, and the second direction can be counterclockwise. By providing the quick-release structure 70, the foam spray tank 1 can quickly complete the engagement or disengagement between the tank body 20 and the cover body 30, which is convenient for the replacement of the solution and other work, saving the working time of the workers, improving the working efficiency, and enhancing the user experience.

To further explain, when the first engaging structure 71 and the second engaging structure 72 are engaged, the air outside the bottle body 20 can still flow into the inside of the bottle body 20, so as to maintain the air pressure inside the bottle body 20, and prevent the motor pump 10 from extracting too much solution and causing the internal pressure to be unbalanced, thereby affecting safe use. In some embodiments, the foam spray bottle 1 will not shrink due to the negative pressure inside the bottle caused by the liquid being sucked out, and the transparent air permeable one-way valve 92 in the cover body 30 will naturally inhale air to balance the pressure due to the liquid being sucked out, and the liquid will not flow out when the bottle is tilted.

In some embodiments, as shown in FIG. 5 and FIG. 6 , the first engaging structure 71 is two first engaging ribs 81, and the two first engaging ribs 81 are transversely disposed on opposite sides of the inner edge of the lid 30. The second engaging structure 72 is two second engaging ribs 82, and the two second engaging ribs 82 are transversely disposed on opposite sides of the outer edge of the opening of the pot body 20. The upper edge of the first engaging rib 81 and the lower edge of the second engaging rib 82 are corresponding inclined surfaces, so that when the first engaging structure 71 is engaged with the second engaging structure 72 along the first direction, the upper edge of the first engaging rib 81 can be tightly matched with the lower edge of the second engaging rib 82 to avoid the risk of falling off.

In some embodiments, as shown in FIG. 5 and FIG. 6 , the upper edge of the first engaging rib 81 has a first positioning structure 811, and the lower edge of the second engaging rib 82 has a second positioning structure 822 corresponding to the first positioning structure 811. When the first positioning structure 811 and the second positioning structure 822 are in contact, the first engaging rib 81 and the second engaging rib 82 are positioned to strengthen the connection strength between the first engaging rib 81 and the second engaging rib 82 to avoid the risk of falling off.

1 to 6 , another embodiment of the present invention further provides a quick-release structure 70 for a foam spray bottle 1. The foam spray bottle includes a motor pump 10, a foaming tube 12, a bottle body 20, and a cover 30. The bottle body 20 is used to contain a solution. The cover 30 is used to cover the opening of the bottle body 20 and contain the motor pump 10 and the foaming tube 12. The foaming tube 12 is connected to the motor pump 10 and mixes the air sucked by the motor pump 10 with the solution to form a liquid-gas mixture and generate foam. The quick-release structure 70 includes a first clamping structure 71 and a second clamping structure 72.

The first engaging structure 71 is disposed on the cover 30. The second engaging structure 72 is disposed on the pot body 20. The first engaging structure 71 can engage with the second engaging structure 72 along a first direction, and the first engaging structure 71 can disengage from the engaging state with the second engaging structure 72 along a second direction opposite to the first direction at a travel distance less than half of the circumference of the opening of the pot body 20. When the first engaging structure 71 engages with the second engaging structure 72, the air outside the pot body 20 can still flow into the inside of the pot body 20. In some embodiments, the foam spray bottle 1 will not shrink due to negative pressure inside the bottle caused by the liquid being sucked out. The transparent air-permeable one-way valve 92 in the cover body 30 will naturally inhale air to balance the pressure as the liquid is sucked out, and the liquid will not flow out when the bottle is tilted.

In some embodiments, the foam sprayer 1 further includes a first pipe 16, a second pipe 18, and a nozzle 14. One end of the first pipe 16 is connected to the motor pump 10 for inputting air into the motor pump 10. One end of the second pipe 18 is connected to the motor pump 10. The other end of the second pipe 18 can extend to the solution in the tank body 20 for inputting the solution into the motor pump 10. The nozzle 14 is connected to the other end of the foaming tube 12 for spraying foam.

In some embodiments, the first locking structure 71 is two first locking ribs 81, which are laterally arranged on opposite sides of the inner edge of the cover body 30, and the second locking structure 72 is two second locking ribs 82, which are laterally arranged on opposite sides of the outer edge of the opening of the pot body 20. The upper edge of the first locking rib 81 and the lower edge of the second locking rib 82 are corresponding inclined surfaces. When the first locking structure 71 is engaged with the second locking structure 72 along the first direction, the upper edge of the first locking rib 81 will be tightly matched with the lower edge of the second locking rib 82.

In some embodiments, the upper edge of the first engaging rib 81 has a first positioning structure 811, and the lower edge of the second engaging rib 82 has a second positioning structure 822 corresponding to the first positioning structure 811. When the first positioning structure 811 and the second positioning structure 822 are in contact, the first engaging rib 81 and the second engaging rib 82 are positioned.

The above preferred specific embodiments are described in detail to more clearly describe the features and spirit of the present invention, but are not intended to limit the scope of the present invention by the preferred specific embodiments disclosed above. On the contrary, the purpose is to cover various changes and arrangements with equivalents within the scope of the patent application for the present invention.
