Description

Technical Field

[0001] The present invention relates to the technical field of sprayers, and particularly to an oral sprayer. Background Art

[0002] With the improvement of people's living standards, oral health problems have been increasingly emphasized. Oral problems such as bad breath, oral ulcers, and gum inflammation not only affect personal social interaction and quality of life but may also trigger systemic diseases. Oral sprayers have gradually become popular oral care products due to their advantages such as convenient use and the ability to quickly relieve oral discomfort.

[0003] As described in a kind of oral care device with the patent number CN111529907B, by setting an airbag, it is conducive to the automatic reset of the pressing head after being squeezed to realize the reciprocating motion of the piston, thereby inflating the airbag. When the volume of the airbag increases after inflation, the pressure inside the housing is increased, and then high-pressure liquid medicine is generated. However, in the actual use process, when the liquid inside the bottle body is not full, when it is necessary to spray the upper palate or the upper posterior alveolar of the oral cavity, the bottle body often needs to be tilted or inverted. The liquid level inside the bottle body will not be able to submerge the suction port of the spray pipe due to tilting or inversion, and thus effective spraying can no longer be carried out. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the prior art and propose an oral sprayer.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] An oral sprayer includes a bottle body. A pressing assembly is provided above the bottle body. When held by hand, the hand-held pressing provides kinetic energy. A transmission area, a liquid storage area, and a liquid pumping area are provided inside the bottle body. A liquid pumping assembly is provided in the liquid pumping area. The liquid pumping assembly can be assisted by the pressing assembly to slide up and down, thereby sucking and pumping out the liquid in the liquid storage area.

[0007] A liquid storage assembly is provided in the liquid storage area. The liquid storage assembly is used to store the liquid in the liquid storage area and the gas pumped in by the liquid pumping assembly. The pressing assembly and the liquid pumping assembly are connected in series through the liquid storage assembly. A second piston is provided in the liquid storage assembly. The interior of the liquid storage assembly is divided into a gas pumping part and a liquid pumping part by the second piston. When the liquid pumping assembly slides up and down, it can push the second piston to slide back and forth. When the second piston slides back and forth, it can pump out and pump in the gas and liquid in the gas pumping part and the liquid pumping part.

[0008] Preferably, a transmission assembly, a clamping mechanism, and a synchronization mechanism are provided in the transmission area. The transmission assembly is used to drive the clamping mechanism and the synchronization mechanism. The transmission assembly consists of a rotating mechanism and a sliding mechanism. A rotating wheel is provided in the rotating mechanism. The rotating wheel is arranged above the bottle body. When the rotating mechanism is held by hand, kinetic energy is provided by hand rotation. The sliding mechanism can be driven by the rotating mechanism to perform a forward and backward sliding action.

[0009] Preferably, the synchronization mechanism is fixedly connected to the rotating mechanism, and the clamping mechanism is fixedly connected to the sliding mechanism. When the rotating mechanism operates, it can drive the sliding mechanism and the clamping mechanism to slide forward and backward. When the rotating mechanism operates, the synchronization mechanism rotates synchronously.

[0010] Preferably, two sets of the sliding mechanism and the clamping mechanism are provided, and the two sets of the sliding mechanism and the clamping mechanism are synchronized by the synchronization mechanism.

[0011] Preferably, a push rod is provided in the liquid pumping assembly, and the clamping mechanism is used to clamp the push rod from both sides.

[0012] Preferably, a guide rod is provided in the transmission area, and a rack is provided in the sliding mechanism. The rack slides forward and backward on the guide rod.

[0013] Preferably, a cap is provided above the bottle body, and a receiving body is provided in the cap.

[0014] Preferably, two sealing gaskets are provided in the bottle body. The sealing gaskets divide the interior of the bottle body into a transmission area, a liquid storage area, and a liquid pumping area.

[0015] The present invention has the following beneficial effects:

[0016] 1. In the present invention, when the pressing assembly presses downward, it can push the push rod to slide downward, thereby driving the first piston in the liquid pumping assembly to pump air downward. The gas enters the air pumping part through the air pipe, and then pushes the second piston to slide forward, pushing the liquid in the liquid pumping part out through the three-head suction pipe and finally atomizing and spraying out from the nozzle. When the second piston returns to its original position, the liquid in the liquid storage area is first transferred to the liquid pumping part through the liquid inlet pipe and then pumped out, effectively avoiding the situation that when the liquid in the liquid storage area is used up by half, the liquid level cannot submerge the suction inlet of the spray pipe due to tilting or inversion, resulting in ineffective spraying.

[0017] 2. In the present invention, the rotating mechanism can drive the sliding mechanism, and with the assistance of the synchronization mechanism, the clamping ring in the clamping mechanism can clamp the push rod from both sides, effectively avoiding the liquid from being sprayed out due to accidental contact with the nozzle when the sprayer is not in use.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1:

[0027] Referring to Figures 2 - 5 , an oral sprayer includes a bottle body 1. There is a pressing component above the bottle body 1. When held by hand, the hand - held pressing provides kinetic energy. Inside the bottle body 1, there are a transmission area 29, a liquid storage area 30, and a liquid pumping area 31. A liquid pumping component is provided in the liquid pumping area 31. The liquid pumping component can be assisted by the pressing component to slide up and down, thereby sucking and pumping out the liquid in the liquid storage area.

[0028] Referring to Figures 2 - 4, a liquid storage assembly is provided in the liquid storage area 30. The liquid storage assembly is used to store the liquid in the liquid storage area 30 and the gas pumped by the liquid pumping assembly. The pressing assembly and the liquid pumping assembly are connected in series through the liquid storage assembly. A second piston 23 is provided in the liquid storage assembly. The interior of the liquid storage assembly is divided into a gas pumping part and a liquid pumping part by the second piston 23. When the liquid pumping assembly slides up and down, it can push the second piston 23 to slide back and forth. When the second piston 23 slides back and forth, it can pump out and pump in the gas and liquid in the gas pumping part and the liquid pumping part.

[0029] A screwing cap 3 is provided above the bottle body. A receiving body 28 is provided inside the screwing cap 3.

[0030] Two sealing gaskets 32 are provided inside the bottle body 1. The sealing gaskets 32 divide the inside of the bottle body 1 into a transmission area 29, a liquid storage area 30, and a liquid pumping area 31.

[0031] In this embodiment, as Figure 2 , Figure 3 , Figure 6 shown, the pressing assembly can specifically adopt the following structure:

[0032] The pressing assembly is composed of a nozzle 2, a straw 27, a connecting body 10, and a liquid inlet hole 34. The screwing cap 3 is threadedly connected to the mouth of the bottle body 1. The receiving body 28 is arranged inside the screwing cap 3 and is connected to the mouth of the bottle body 1. The nozzle 2 is rotatably connected to the straw 27. The straw 27 passes through the receiving body 28 and is fixedly connected above the liquid inlet hole 34 in the connecting body 10.

[0033] Referring to Figure 2 , Figure 4 shown, the liquid pumping assembly can specifically adopt the following structure:

[0034] The liquid pumping assembly is composed of a push rod 5, a first piston 25, an air cylinder 19, a first spring 26, and an air pipe 12. The upper end of the push rod 5 is fixedly connected to the lower end of the connecting body 10. The lower end of the push rod 5 is fixedly connected to the first piston 25. The push rod 5 passes through and is slidably connected to the two sealing gaskets 32. The first piston 25 is connected to the bottom end of the air cylinder 19 through the first spring 26. One end of the air pipe 12 is fixedly connected through the air cylinder 19. The air cylinder 19 is arranged below the liquid pumping area. The first piston 25 is slidably arranged inside the air cylinder 19. Through the pressing of the pressing assembly and the resetting action of the first spring 26, the first piston 25 slides up and down inside the air cylinder 19, and pumps out the gas inside the air cylinder 19 through the air pipe 12.

[0035] Referring to Figure 2 , Figure 4 shown, the liquid storage assembly can specifically adopt the following structure:

[0036] The liquid storage assembly is composed of a liquid storage tank 6, a second piston 23, a second spring 33, a liquid inlet pipe 24, and a three - headed suction pipe 11. The liquid storage tank 6 is arranged on the gasket 32 in the liquid storage area 30. The liquid storage tank 6 is composed of a gas pumping part and a liquid pumping part. The gas pumping part and the liquid pumping part are separated by the second piston 23. The left side of the second piston is connected to the side wall of the liquid storage tank 6 through the second spring 33. The other end of the air pipe 12 is connected through - penetration to the lower end of the liquid pumping part. Two of the ends of the three - headed suction pipe 11 are respectively connected through - penetration to the side walls of the corresponding liquid pumping parts, and the other end is fixedly connected to the lower end of the liquid inlet hole 34. It should be noted that one - way valves are provided at both ends of the three - headed suction pipe 11 where it is connected through - penetration to the liquid pumping part and inside the liquid inlet pipe 24.

[0037] In this embodiment, the liquid pumping assembly can be driven to act by pressing the pressing assembly. Meanwhile, with the auxiliary effect of the liquid storage assembly, the liquid in the liquid storage area is first sucked in and then pumped out.

[0038] When holding the bottle body 1 and pressing the nozzle 2, the nozzle 2 pushes the suction pipe 27 and the connector 10 downward, and further causes the push rod 5 to push the first piston 25 downward. The first piston 25 squeezes downward to expel the gas in the lower part of the air cylinder 19 through the air pipe 12 into the gas pumping part of the liquid storage tank 6. The second piston 23 slides to the right to squeeze the liquid in the liquid pumping part through the three - headed suction pipe 11 into the connector 10 and the suction pipe 27, and finally sprays out atomized through the nozzle 2. It should be noted that when the liquid pumping part is in its initial state and has not been used, it is filled with a part of gas, so the gas in the liquid pumping part is discharged first during the first squeeze. When the finger is released, the first piston 25, the push rod 5, the connector 10, and the suction pipe 27 reset under the action of the first spring 26, and the second piston 23 resets under the action of the second spring 33. When the second piston 23 resets, it sucks the liquid in the liquid storage area 30 into the liquid pumping part through the liquid inlet pipe 24. When the nozzle 2 is pressed again, the liquid in the liquid pumping part can be sprayed out atomized.

[0039] Embodiment Two:

[0040] In this embodiment, referring to Figure 2 、 Figure 4 、 Figure 5 , a transmission assembly, a clamping mechanism, and a synchronization mechanism are provided in the transmission area 29. The transmission assembly is used to drive the clamping mechanism and the synchronization mechanism. The transmission assembly is composed of a rotation mechanism and a sliding mechanism. A rotating wheel 4 is provided inside the rotation mechanism. The rotating wheel 4 is arranged above the bottle body 1. When the rotation mechanism is held by hand, kinetic energy is provided by hand rotation. The sliding mechanism can be driven by the rotation mechanism to perform a forward - and - backward sliding action.

[0041] The synchronization mechanism is fixedly connected to the rotation mechanism, and the clamping mechanism is fixedly connected to the sliding mechanism. When the rotation mechanism acts, it can drive the sliding mechanism and the clamping mechanism to slide forward and backward, and the synchronization mechanism rotates synchronously when the rotation mechanism acts.

[0042] Two groups of sliding mechanisms and clamping mechanisms are provided, and the two groups of sliding mechanisms and clamping mechanisms are synchronized by a synchronization mechanism.

[0043] A push rod 5 is arranged in the pump assembly, wherein the clamping mechanism is used to clamp the push rod 5 from both sides.

[0044] A guide rod 21 is provided in the transmission area 29 , and a rack 20 is provided in the sliding mechanism. The rack 20 slides back and forth on the guide rod 21 .

[0045] In this embodiment, the rotating mechanism and the synchronous mechanism may specifically adopt the following structures:

[0046] The rotating mechanism is composed of a rotating wheel 4, a first rotating rod 7, a second rotating rod 8, and a third rotating rod 9, and the synchronous mechanism is composed of two first rotating wheels 13, two second rotating wheels 14, a first synchronous belt 17, and a second synchronous belt 18. The lower ends of the first rotating rod 7, the second rotating rod 8, and the third rotating rod 9 are rotatably arranged on the sealing gasket 32 ​​at the lower part of the transmission area 29, and the upper ends are rotatably connected to the upper part of the bottle body 1. A section above the first rotating rod 7 is exposed from the bottle body 1 and is fixedly connected to the rotating wheel 4. The two first rotating wheels 13 are respectively fixedly connected to the first rotating rod 7 and the second rotating rod 8, and the two first rotating wheels 13 are connected by the first synchronous belt 17. The two second rotating wheels 14 are respectively fixedly connected to the second rotating rod 8 and the third rotating rod 9, and the two second rotating wheels 14 are connected by the second synchronous belt 18.

[0047] The sliding mechanism and the clamping mechanism may specifically adopt the following structures:

[0048] The sliding mechanism is composed of a rack 20 and a gear 15, the clamping mechanism is composed of a connecting rod 22 and a clamping ring 16, the guide rod 21 is fixedly connected to the inner wall of the bottle body 1, the rack 20 is slidably connected to the guide rod 21, the gear 15 is respectively fixedly connected to the first rotating rod 7 and the third rotating rod 9, and the rack 20 is meshed with the gear 15. The connecting rod 22 is fixedly connected to the right side of the rack 20, and the rack 20 is fixedly connected to the clamping ring 16.

[0049] In this embodiment, the sliding mechanism can be driven by the rotating mechanism, and with the assistance of the synchronization mechanism, the clamping mechanism can clamp the push rod 5 from both sides.

[0050] When the device is not in use, the rotating wheel 4 can be rotated, which drives the first rotating rod 7 to rotate, causing the gear 15 to rotate, driving the rack 20 to slide, and synchronously driving the connecting rod 22 and the clamping ring 16 to slide. At the same time, when the first rotating rod 7 rotates, the two first rotating wheels 13 are driven by the first synchronous belt 17, and the second rotating rod 8 rotates. The two second rotating wheels on the second rotating rod 8 and the third rotating rod 9 are driven by the second synchronous belt 18, further driving another set of sliding mechanisms and clamping mechanisms to slide. The two clamping mechanisms slide relatively to clamp the push rod 5. It should be noted that a part of the lower end of the connecting body 10 has a diameter slightly larger than that of the push rod 5, and the two clamping rings 16 can be clamped at the intersection of the lower end of the connecting body 10 and the upper end of the push rod 5. When the mis-touched nozzle 2 is pressed downward, the lower end of the connecting body 10 can also be clamped by the clamping rings 16.

[0051] As mentioned above, the above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
