Description

Technical Field

[0001] The utility model relates to the technical field of foam spray pots, in particular to an electric foam spray pot. Background Art

[0002] A spray bottle is a spray device that uses the pressure inside the bottle to spray the liquid outward. It is small in size, easy to carry and hand-held. It is widely used in indoor room cleaning, various equipment cleaning, car interior and exterior cleaning, wall cleaning and other scenarios. A foam spray bottle is one type of spray bottle. It uses the same principle to spray rich foam and is also common in daily life.

[0003] The foam sprayer is composed of an air compression device, a liquid storage bottle, a pipette, a nozzle, etc. According to the different driving methods of the air compression device, the foam sprayer is divided into a manual foam sprayer and an electric foam sprayer. Since the electric foam sprayer does not require frequent hand-compressed air operations when used, it is very convenient and labor-saving. In addition, the electric foam sprayer generates pressure quickly, and the pressure value generated is also greater, the foaming effect is better, and the spraying distance is also longer, so it has become more and more popular in recent years.

[0004] The liquid storage bottle on the manual foam sprayer or the electric foam sprayer adopts a detachable structure. When the liquid in the liquid storage bottle is used up, the liquid storage bottle can be removed and the liquid can be refilled, and then finally installed back for continued use; but unlike the manual foam sprayer, the electric foam sprayer is equipped with an electric booster pump that can automatically pressurize the liquid storage bottle, and is also equipped with a battery for providing power to the electric booster pump.

[0005] The existing electric foam spray bottle lacks a quick deflation function. When the liquid in the liquid storage bottle is exhausted and the liquid storage bottle needs to be removed, the bottle mouth connection of the liquid storage bottle will be subject to greater resistance due to the greater air pressure remaining in the liquid storage bottle. A greater external force must be used to remove the liquid storage bottle. If the user's hand strength is small, it cannot be opened, which is inconvenient to use; and when the bottle mouth connection is forcibly opened under the condition of greater resistance, it is easy to cause damage to the bottle mouth connection; so the switch pressing plate of the electric foam spray bottle can only be pressed again and kept for a certain time to discharge the air pressure remaining in the liquid storage bottle through the original foam spraying channel, but because the original foam spraying channel is relatively narrow, the exhaust speed is slow, and it takes a certain time to completely empty, so the pressure relief efficiency is low, resulting in low convenience of use; in addition, if the existing electric foam spray bottle is in a state of continuously spraying foam, it is necessary to continuously press the switch pressing plate of the electric foam spray bottle by hand, and after a long time, the fingers will be sore, the use is laborious and not humane, and the practicality is poor, which needs further improvement.

A clamping strip 42 is also formed outward at the ends of the two guide pieces 41. The two clamping strips 42 are slidably fitted on the lower outer wall of the end of the pressing handle 13.

[0044] A convex strip 43 arranged transversely upward is formed on the top outer wall of the locking block 4 to facilitate the force of the fingers.

[0045] Directions:

[0046] Remove the bottom cover 18 and place the matching number and specifications of dry batteries into the handle cavity 115 in the specified direction, then install the bottom cover 18 back to its original position to connect each dry battery into a group with the help of the conductive spring arranged on the inner side of the bottom cover 18, and then use the two connecting springs arranged at the upper opening of the handle cavity 115 to overlap the positive and negative poles of the dry battery group after the series connection, because the two connecting springs are respectively electrically connected to the positive and negative terminals of the electric booster pump 14 through wires, the positive and negative poles of the dry battery group after the series connection are respectively connected to the positive and negative terminals of the electric booster pump 14. The above structure and principle are all prior arts; a part of the structure of the electric booster pump 14 and the wires used to connect the two connecting springs are arranged in the groove cavity 114, and the electric booster pump 14, the two connecting springs and the two wires can be disassembled, assembled and repaired by removing the top cover 17.

[0047] When in use, hold the outside of the handle cavity 115 with your hand and press the end of the pressure handle 13 downward with your thumb, the pressure handle 13 will start the switch provided on the electric booster pump 14 to energize the electric booster pump 14, and then the electric booster pump 14 will continue to fill air into the liquid storage bottle 2 to increase the internal pressure. At this time, the liquid inlet of the spray head 12 will be in a passage state during the process of pressing the end of the pressure handle 13 downward, and the pressure in the liquid storage bottle 2 will continue to increase, which will push the liquid in the liquid storage bottle 2 into the spray head 12 through the liquid inlet pipe 16, and then spray foam outward through the liquid outlet of the spray head 12; if the thumb releases the end of the pressure handle 13, the pressure handle 13 will swing upward and reset using the elastic recovery function, so that the liquid inlet of the spray head 12 returns to the disconnected state and the electric booster pump 14 is turned off, thereby preventing the liquid in the liquid storage bottle 2 from entering the spray head 12 through the liquid inlet pipe 16, and then stopping the spraying of foam. The above structure and principle are all prior art.

[0048] The advantage of the present invention is that when the liquid in the liquid storage bottle 2 is exhausted, a large pressure is still maintained in the liquid storage bottle 2, and the above-mentioned pressure will generate a large additional resistance to the connection between the shell 11 and the opening of the liquid storage bottle 2. At this time, if the liquid storage bottle 2 is to be removed, a large external force is required to remove the liquid storage bottle 2; but the present invention is provided with an exhaust module 3. Under normal circumstances, the return spring 32 will exert a downward force on the lifting block 31 to press the sealing ring 33 against the bottom wall of the shell 11, thereby closing the exhaust hole 111; if the liquid storage bottle 2 is to be removed, the rectangular protrusion 313 on the lifting block 31 is pushed upward by hand to make it move upward in the rectangular hole 154 until the upper outer wall of the rectangular protrusion 313 touches the upper inner wall of the rectangular hole 154, thereby making the guide column 311 move up along the guide sleeve 112, thereby driving the sealing ring 33 to move up synchronously with the help of the positioning column 312 to leave the bottom inner wall of the shell 11, until The cam 312 is pressed against the bottom wall of the housing 110 and the pressure relief valve 314 is lifted up to the top of the housing 110, and the pressure relief valve 314 is lifted up to the top of the housing 110, so that the pressure relief valve 314 can be lifted up.

[0049] In addition, if it is necessary to spray foam for a long time and you do not want to press the end of the pressure handle 13 for a long time, you can move the locking block 4 to the bottom in the direction away from the movable groove 151 until the end of the locking block 4 away from the movable groove 151 abuts against the inner wall of the end of the sink cavity 131 away from the movable groove 151. At this time, the end of the locking block 4 close to the movable groove 151 is located on the outside of the stopper 152; when the finger releases the end of the pressure handle 13 to make the end of the pressure handle 13 swing upward and reset, the end of the locking block 4 close to the movable groove 151 will abut against the outer wall of the outer side of the stopper 152 to prevent the end of the pressure handle 13 from swinging upward and resetting, thereby keeping the end of the pressure handle 13 in the pressed position, so that the electric foam sprayer remains in a working state of continuously spraying foam.

[0050] The utility model can use the exhaust module 3 to quickly release the air pressure remaining in the liquid storage bottle 2 so that the electric foam sprayer has a one-button deflation function, thereby quickly eliminating the large additional resistance between the opening of the liquid storage bottle 2 and the shell 11, and there is no need to discharge the air pressure remaining in the liquid storage bottle through the original foam spraying channel, so that the internal pressure of the liquid storage bottle 2 can be emptied in a short time to improve the pressure relief efficiency, thereby effectively improving the convenience of use. The user's hand only needs to use normal force to easily remove the liquid storage bottle 2, which is convenient for operation and will not cause damage to the opening of the liquid storage bottle 2; in addition, the utility model can also use the sliding locking block 4 to enable the electric foam sprayer to automatically maintain a state of continuous foam spraying to improve practicality, and there is no need to continuously press the end of the pressure handle 13 by hand. It is both labor-saving and humane when used, and it is easy to operate.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
