Description

Technical Field

[0001] The utility model relates to an atomizer, in particular to an atomizer with a noise reduction function. Background Art

[0002] A nebulizer uses oxygen or ultrasound to atomize liquid medicine into tiny particles, which are then inhaled into the respiratory tract and lungs for deposition, thereby achieving the purpose of painless and rapid treatment of diseases. A nebulizer can be used to treat pharyngitis, bronchitis, pneumonia, etc., but it needs to be done under the guidance of a doctor.

[0003] However, existing atomizers make a lot of noise during use. When using the atomizer, liquid is first poured into the atomizer, and the atomizer vibrates water molecules into water mist. The vibration frequency is relatively high during the process of the water molecules vibrating into water mist, and the vibration generates a huge noise. When people use the atomizer, the noise may make people feel uncomfortable.

[0004] Therefore, we need to design an atomizer with noise reduction function. Utility Model Content

[0005] In order to overcome the shortcoming of existing atomizers that make a lot of noise during use, the technical problem of the utility model is to provide an atomizer with a noise reduction function.

[0006] The technical implementation scheme of the utility model is: an atomizer with a noise reduction function, including a shell, a soundproof cover, a lower spring pad, an upper spring pad, a first spring, a placement plate, an atomizer, a nozzle, a first water inlet pipe, a solenoid valve, a second water inlet pipe and a controller, a lower cavity is opened at the lower inner part of the shell, a soundproof cover is provided on the inner wall of the lower cavity, four lower spring pads are fixedly connected to the bottom of the inner side of the soundproof cover, the inner sides of the four lower spring pads are all slidably connected to the upper spring pad, the contact surface of the lower spring pad and the upper spring pad is coated with a damping material, the first spring is connected between the lower spring pad and the upper spring pad, and the tops of the four upper spring pads are connected. A placement plate is fixedly connected, an atomizer is fixedly connected to the top of the placement plate, a nozzle is fixedly connected to the front side of the atomizer, the nozzle passes through the sound insulation cover and the front side of the shell, an upper cavity is opened on the upper inner side of the shell, a first water inlet pipe is fixedly connected to the top of the atomizer, the lower end of the first water inlet pipe passes through the inside of the atomizer, the upper end of the first water inlet pipe passes through the top of the sound insulation cover and passes through the upper cavity of the shell, a solenoid valve is fixedly connected to the lower part of the first water inlet pipe, a second water inlet pipe is fixedly connected to the top of the shell, the second water inlet pipe passes through the upper cavity of the shell, a controller is fixedly connected to one side of the shell, and the controller is electrically connected to the atomizer and the solenoid valve.

[0007] In a preferred embodiment of the present invention, the upper portion of the housing is made of transparent plastic.

[0008] In a preferred embodiment of the present invention, a thread pattern is provided on the upper portion of the second water inlet pipe.

[0009] In a preferred embodiment of the present invention, it also includes a cover, a second spring and a muffler. The cover is threadedly connected to the upper part of the second water inlet pipe. An opening is opened in the middle of the front side of the shell. The second spring is connected between the inner side wall of the opening and the nozzle, and a muffler is installed at the front end of the nozzle.

[0010] In a preferred embodiment of the present invention, a rotating rod and a storage plate are further included. The lower left side of the shell is fixedly connected to the rotating rod, and the storage plate is rotatably connected to the rotating rod.

[0011] In a preferred embodiment of the present invention, the surface of the rotating rod is coated with a damping material.

[0012] Compared with the prior art, the present invention has the following advantages: 1. By setting the first spring, the first spring will undergo elastic deformation due to the vibration of the placement plate and the upper spring pad. This deformation will absorb part of the vibration energy, thereby reducing the vibration transmitted to the outer shell. The first spring has an elastic restoring force. When the external force disappears, the first spring will try to return to its original shape. During this recovery process, the first spring will convert the absorbed energy into elastic potential energy, further reducing the vibration.

[0013] 2. By setting a cover and tightening the cover clockwise on the second water inlet pipe, the upper part of the shell can be sealed, which can isolate a certain amount of noise.

[0014] 3. By setting up the second spring, the second spring will be elastically deformed due to the vibration of the nozzle. The shock absorption principle is the same as that of the first spring, further reducing noise.

[0015] 4. By setting up the solenoid valve, the switch of the solenoid valve can be controlled by the controller, so that the amount of liquid in the upper cavity flowing into the atomizer through the first water inlet pipe can be arbitrarily controlled.

[0016] 5. By setting a silencer, the noise is transmitted from the nozzle. The silencer at the nozzle is based on the spectrum of the jet noise. If the total area of ​​the nozzle remains unchanged and is replaced by many small nozzles, when the air flow passes through the small holes, the spectrum of the jet noise will shift to high frequency or ultra-high frequency, which will significantly reduce the audible sound components in the spectrum, thereby reducing the noise emitted by the nozzle and reducing interference and harm to people.

[0017] 6. By setting up the storage board, pull the storage board down by hand, and then you can place items on the storage board. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] First of all, it should be noted that in the various embodiments described, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.

[0025] Embodiment: A kind of atomizer with noise reduction function, such as Figure 1 、 Figure 2 and Figure 3As shown, it includes a shell 1, a soundproof cover 3, a lower spring pad 4, an upper spring pad 5, a first spring 6, a placement plate 7, an atomizer 8, a nozzle 801, a first water inlet pipe 9, a solenoid valve 10, a second water inlet pipe 12 and a controller 13. A lower cavity 2 is opened at the lower inner part of the shell 1, and a soundproof cover 3 is provided on the inner wall of the lower cavity 2. Two lower spring pads 4 are connected to the front and rear sides of the bottom of the inner side of the soundproof cover 3 by screws. The inner sides of the four lower spring pads 4 are all slidably connected to the upper spring pad 5. The contact surface between the lower spring pad 4 and the upper spring pad 5 is coated with a damping material. A first spring 6 is connected between the lower spring pad 4 and the upper spring pad 5. A placement plate 7 is connected between the tops of the four upper spring pads 5 by screws. The top of the placement plate 7 is connected to the atomizer 8 by bolts. When the atomizer vibrates, the placement plate 7 and the upper spring pad 5 vibrate. The first spring 6 will undergo elastic deformation due to the vibration of the placement plate 7 and the upper spring pad 5. This deformation will absorb part of the vibration energy, thereby reducing the vibration transmitted to the housing 1 and further reducing noise. The first spring 6 has elastic restoring force. When the external force disappears, the first spring 6 will try to Figure returns to its original shape. During this recovery process, the first spring 6 will convert the absorbed energy into elastic potential energy to further reduce vibration. The front side of the atomizer 8 is fixedly connected with a nozzle 801. The nozzle 801 passes through the sound insulation cover 3 and the middle of the front side of the shell 1. An upper cavity 11 is opened on the upper inner side of the shell 1. The top and rear side of the atomizer 8 are fixedly connected with a first water inlet pipe 9. The lower end of the first water inlet pipe 9 passes through the inside of the atomizer 8. The upper end of the first water inlet pipe 9 passes through the top of the sound insulation cover 3 and passes through the upper cavity 11 of the shell 1. The lower end of the first water inlet pipe 9 passes through the top of the sound insulation cover 3 and passes through the upper cavity 11 of the shell 1. The upper part of the shell 1 is connected to the solenoid valve 10 by bolts, and the second water inlet pipe 12 is connected to the rear side of the top of the shell 1 by screws. The second water inlet pipe 12 is inserted into the upper cavity 11 of the shell 1. The right side of the shell 1 is fixedly connected to the controller 13. The controller 13 is electrically connected to the atomizer 8 and the solenoid valve 10. The switch of the solenoid valve 10 can be controlled by the controller 13, so that the amount of liquid in the upper cavity 11 flowing into the atomizer 8 through the first water inlet pipe 9 can be arbitrarily controlled. The upper part of the shell 1 is made of transparent plastic material, and the upper part of the second water inlet pipe 12 is provided with a threaded pattern.

[0026] like Figure 4As shown, it also includes a cover 14, a second spring 16 and a muffler 17. The cover 14 is threadedly connected to the upper part of the water inlet pipe. When the cover 14 is tightened clockwise on the second water inlet pipe 12, the upper part of the housing 1 can be sealed, which can isolate a certain amount of noise. An opening 15 is opened in the middle of the front side of the housing 1. A second spring 16 is connected between the inner wall of the opening 15 and the nozzle 801. The second spring 16 will elastically deform due to the vibration of the nozzle 801. The shock absorption principle is the same as that of the first spring 6, which further reduces noise. A muffler 17 is installed at the front end of the nozzle 801, and the noise is transmitted from the nozzle 801. The muffler 17 at the nozzle 801 is based on the spectrum of the jet noise. If the total area of ​​the nozzle remains unchanged and is replaced by many small nozzles, when the air flow passes through the small holes, the spectrum of the jet noise will shift to high frequency or ultra-high frequency, so that the audible sound component in the spectrum is significantly reduced, thereby reducing the noise emitted from the nozzle 801 and reducing interference and harm to people.

[0027] like Figure 5 As shown, it also includes a rotating rod 18 and a storage plate 19. The rotating rod 18 is fixedly connected to the lower left side of the shell 1, and the storage plate 19 is rotatably connected to the rotating rod 18. The surface of the rotating rod 18 is coated with damping material. The storage plate 19 is pulled downward by hand, and items can be placed on the storage plate 19 at this time.

[0028] When the device needs to be used, first unscrew the cover 14 counterclockwise by hand, and then input the liquid into the upper cavity 11 from the second water inlet pipe 12. The water level can be observed through the upper part of the shell 1. When the water level reaches a suitable height, stop inputting the liquid into the second water inlet pipe 12, so that the liquid is stored in the upper cavity 11 of the shell 1. Then tighten the cover 14 clockwise by hand, so that the upper part of the shell 1 is sealed, which can isolate a certain amount of noise. Then start the solenoid valve 10 through the controller 13, and the solenoid valve 10 opens, so that the liquid flows from the first water inlet pipe 9 into the atomizer 8. The switch of the solenoid valve 10 can be controlled by the controller 13, so that the amount of liquid in the upper cavity 11 flowing into the atomizer 8 through the first water inlet pipe 9 can be controlled at will. Then start the atomizer 8 through the controller 13, and the atomizer 8 atomizes the liquid and sprays it from the nozzle 801.

[0029] The atomizer 8 will vibrate during operation, thereby making noise. When the atomizer 8 vibrates, the placement plate 7 and the upper spring pad 5 will vibrate. The first spring 6 will elastically deform due to the vibration of the placement plate 7 and the upper spring pad 5. This deformation will absorb part of the vibration energy, thereby reducing the vibration transmitted to the housing 1, and further reducing noise. The first spring 6 has an elastic restoring force. When the external force disappears, the first spring 6 will try to return to its original shape. During this recovery process, the first spring 6 will convert the absorbed energy into elastic potential energy, further reducing vibration. When the atomizer 8 vibrates, the nozzle 801 will vibrate. The second spring 16 will elastically deform due to the vibration of the nozzle 801. The shock absorption function is as described above.

[0030] Most of the noise generated by the vibration of the atomizer 8 is transmitted from the nozzle 801. The silencer 17 at the nozzle 801 is based on the spectrum of the jet noise. If the total area of ​​the nozzle remains unchanged and is replaced by many small nozzles, when the air flow passes through the small holes, the spectrum of the jet noise will shift to high frequency or ultra-high frequency, which will significantly reduce the audible sound components in the spectrum, thereby reducing the noise emitted by the nozzle 801 and reducing interference and harm to people.

[0031] When you need to place items, just pull the storage plate 19 downwards by hand, and the storage plate 19 will rotate counterclockwise along the rotating rod 18. When the storage plate 19 is pulled to a suitable position, stop pulling the storage plate 19 and you can place items on it.

[0032] While the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that various other embodiments can be devised without departing from the scope of the invention. Accordingly, the scope of the invention should be limited only by the claims appended hereto.
