Description

Technical Field

[0001] The utility model relates to the technical field of nasal aspirators, in particular to a flow guide bracket, a nasal aspirator suction chamber group and a nasal aspirator. Background Art

[0002] When infants and young children have secretions in their nasal cavity and they are unable to clear them by themselves, the secretions dry in the nasal cavity and cause blockage of the nostrils. A nasal aspirator is a tool that helps infants and young children to clean up the secretions in the nasal cavity and unclog the respiratory tract. The nasal aspirator is used to suck out the mucus in the nasal cavity. Its working principle is to use the suction pump inside the nasal aspirator to achieve the purpose of sucking out the mucus.

[0003] However, during the process of sucking out snot from the nose, the existing nasal aspirator cannot effectively block the snot due to the unreasonable structural design of the guide bracket inside the nasal aspirator, which causes the snot to easily enter the airway through the suction hole of the guide bracket, causing blockage inside the airway, and even enter the suction pump and other equipment, causing malfunction of the nasal aspirator. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a diversion bracket, which has the advantages of fast diversion speed and can effectively prevent liquid from entering the airway from the suction hole. It is suitable for the suction chamber group of the nasal aspirator and the blocking and diversion of nasal mucus in the nasal aspirator, preventing nasal mucus from entering the airway and avoiding damage to the suction pump of the nasal aspirator and other equipment.

[0005] The utility model is realized by the following technical solutions:

[0006] A flow guide bracket comprises a bracket body and two arched baffles, wherein an airway is arranged inside the bracket body; the arched baffles form a flow baffle cavity, and the two arched baffles are respectively vertically arranged on the side walls on both sides of the bracket body and open outward; air suction holes are respectively opened on the side walls of the bracket body at corresponding positions of each of the arched baffles, and the air suction holes are connected with the airway and the flow baffle cavity; the two arched baffles and the outer side surface of the bracket body enclose a flow guide groove.

[0007] The flow guide bracket described in the utility model is provided with arched baffles on the side walls on both sides of the bracket body, and the opening of the arched baffles on the bracket body faces outward, that is, the upper and lower ends of each arched baffle extend outwardly upward and downward from the bracket body, respectively, and the two arched baffles and the outer side surface of the bracket body are enclosed to form a flow guide groove. When the flow guide bracket is used in the nasal aspirator, the snot is blocked and guided by the two arched baffles and the flow guide groove; when the nasal aspirator is working to absorb the snot, the snot falls on the upper part of the two arched baffles or directly falls into the flow guide groove, and the two arched baffles are used to block the snot from falling into the flow blocking cavity, preventing the snot from being sucked into the air intake hole; at the same time, the inclination of the two ends of the two arched baffles and the flow guiding effect of the flow guide groove accelerates the flow guidance of the snot, so that the snot falls quickly, further preventing the snot from being sucked into the air intake hole.

[0008] As a preferred solution, the two arched baffles each include a first baffle, a second baffle and a third baffle; the first baffle is arranged on the side wall of the bracket body, and the air intake hole is opened at the corresponding position of the bracket body and the first baffle; the two sides of the first baffle extend and protrude from the side wall of the bracket body respectively, so that two guide grooves are formed between the first baffles of the two arched baffles and the outer side surface of the bracket body; the second baffle is arranged at the upper end of the first baffle, and is arranged upward and outward from the first baffle; the third baffle is arranged at the lower end of the first baffle, and is arranged downward and outward from the first baffle.

[0009] The utility model designs the structure of the arched guide plate, and when the guide bracket is used in the nasal aspirator, it can block and guide the snot in many aspects to prevent the snot from being sucked into the suction hole; wherein, the utility model sets the two sides of the first baffle plate to extend and protrude from the side walls of the bracket body respectively, so that the first baffle plates of the two arched baffle plates and the outer side surface of the bracket body are surrounded to form two guide grooves, and the snot falling on the guide bracket is guided by the guide effect of the two guide grooves, and at the same time, the suction hole is isolated to prevent the snot from being sucked into the suction hole from the guide groove. air hole; the second baffle is arranged outwardly and upwardly from the upper end of the first baffle, so that the snot falling on the second baffle can be blocked and guided by its inclination, preventing the snot from falling into the baffle cavity or the air suction hole, and preventing the snot from being sucked into the airway from the air suction hole; the third baffle is arranged outwardly and downwardly from the lower end of the first baffle, so that after the snot falls from the guide groove, it can be guided by its inclination, so that the snot falls stably, and at the same time isolate the air suction hole, preventing the snot from being sucked into the airway from the air suction hole during the falling process.

[0010] As a preferred solution, the size of the second baffle is larger than that of the third baffle. With this arrangement, when the flow guide bracket is used in the nasal aspirator, after the snot falls on the second baffle, the snot cannot fall on the third baffle, thereby preventing the snot from falling on the third baffle and causing the snot to enter the airway from the suction hole.

When the flow guide bracket is used in a nasal aspirator, the blocking parts are provided to further prevent mucus from being sucked into the air intake hole from both sides of the first baffle plate and entering the airway when the mucus flows through the flow guide groove.

[0012] As a preferred solution, the two sides of the third baffle are respectively provided with downwardly extending guide parts. When the guide bracket is used in a nasal aspirator, the guide parts can further guide the nasal mucus flowing through the guide groove, so that the nasal mucus can fall stably.

[0013] As a preferred solution, the height position of the upper end of the first baffle plate is higher than the height position of the upper end of the bracket body. This arrangement reduces the blocking effect of the upper end of the bracket body on the snot, further improves the guiding effect of the second baffle plate and the guide groove on the snot, and accelerates the guide and falling of the snot.

[0014] As a preferred solution, the support body is columnar, vertically hollow, open at the lower end and closed at the upper end; a chamfer is provided at the upper end of the support body. By providing the chamfer at the upper end of the support body, snot falling on the upper end of the support body can be accelerated to flow into the guide groove through the chamfer.

[0034] Example 1

[0035] The flow guide bracket of the existing nasal aspirator is not reasonably designed, which may cause mucus to enter the airway from the air suction hole of the flow guide bracket, or even enter the air suction pump and other equipment, resulting in blockage of the airway or nasal aspirator failure. Therefore, the embodiment of the utility model provides a newly designed flow guide bracket 4 and a nasal aspirator suction chamber group 100 containing the flow guide bracket. In order to facilitate a full description of the flow guide bracket of the embodiment of the utility model, the embodiment of the utility model combines the structure of the nasal aspirator suction chamber group to explain the beneficial effects of the flow guide bracket of the utility model.

[0036] The utility model provides a nasal suction device suction chamber assembly 100, please refer to Figure 1-Figure 3 , including a suction bin base 1, a suction bin cover 2, a suction nozzle 3 and a guide bracket 4.

[0037] The suction bin base 1 and the suction bin cover 2 are detachably assembled, and the suction bin base 1 and the suction bin cover 2 enclose a suction bin 10. A suction column 11 is provided in the middle of the suction bin base 1, and the flow guide bracket 4 is installed on the suction column 11 and is located in the suction bin 10. The upper end of the suction bin cover 2 is open, and the suction nozzle 3 is detachably assembled on the suction bin cover 2; the suction column 11 is connected with the flow guide bracket 4, the suction bin 10, the suction bin cover 2, and the suction nozzle 3 in sequence.

[0038] When the suction chamber assembly 100 of the nasal aspirator is used to suck out nasal mucus, the suction column 11 is connected to a suction component such as an air pump (not shown) to form a negative pressure; the suction nozzle 3 is inserted into the nasal cavity, and the nasal mucus is sucked into the upper part of the suction chamber 10 from the lower suction nozzle 3 and the suction chamber cover 2 under the action of the negative pressure; by providing a guide bracket 4, the nasal mucus falls into the lower part of the suction chamber 10 under the action of the guide bracket, thereby preventing the nasal mucus from being sucked into the airway thereof, and further preventing the nasal mucus from being sucked into the suction components such as the air pump and causing damage.

[0039] Specifically, the utility model embodiment provides a newly designed flow guide bracket 4, please refer to Figure 4-Figure 8 , its structure is as follows:

[0040] A guide bracket 4, see Figure 4-Figure 8 , including a bracket body 41 and two arched baffles 42, wherein an airway is arranged in the bracket body 41; the arched baffles 42 form a baffle cavity 420, and the two arched baffles 42 are respectively vertically arranged on the side walls on both sides of the bracket body 41 and open outward; the side walls of the two bracket bodies 41 are respectively provided with suction holes 43 at the corresponding setting positions of each arched baffle 42, and the suction holes 43 are connected with the airway and the baffle cavity 420; the two arched baffles 42 and the outer side surfaces of the bracket body 41 are enclosed to form a guide groove 44.

[0041] The flow guide bracket 4 is provided with an arched baffle plate 42 on the side walls of both sides of the bracket body 41, and the arched baffle plate 42 opens outward on the bracket body 41, that is, the upper and lower ends of each arched baffle plate 42 extend outwardly and obliquely upward and obliquely downward from the bracket body, respectively, and the two arched baffle plates and the outer side surface of the bracket body are enclosed to form a flow guide groove, so that the flow guide bracket 4 can play a role in blocking and guiding the snot. When sucking the snot, the snot falls on the upper part of the two arched baffle plates 42 or directly falls into the two flow guide grooves 44. With the help of the two arched baffle plates 42, the snot is blocked from falling into the flow blocking cavity 420, and the snot is prevented from being sucked into the air intake hole 43; at the same time, with the help of the tilting effect of the two ends of the two arched baffle plates 42 and the flow guiding effect of the two flow guide grooves 44, the flow guidance of the snot is accelerated, so that the snot falls quickly, and the snot is further prevented from being sucked into the air intake hole 43.

[0042] In this example, see Figure 4-Figure 8 The two arcuate baffles 42 each include a first baffle 421, a second baffle 422 and a third baffle 423. By designing the structure of the arcuate baffles 42, mucus can be prevented from being sucked into the air intake hole 43 in many aspects. Among them:

[0043] The first baffle plate 421 is arranged on the side wall of the bracket body 41, and the air suction hole 43 is provided at the corresponding position of the bracket body 41 and the first baffle plate 42. The two sides of the first baffle plate 421 extend and protrude from the side wall of the bracket body 41, so that the first baffle plates 421 of the two arcuate baffle plates 42 and the side wall of the bracket body 41 form two guide grooves 44, that is, the two arcuate baffle plates 42 are spaced apart, and the two sides of the two arcuate baffle plates 42 and the side wall of the bracket body 41 form two guide grooves 44, and the snot falling on the guide bracket 4 is guided by the guiding effect of the two guide grooves 44, and the air suction hole 43 is isolated at the same time, to prevent the snot from being sucked into the air hole 43 from the guide groove 44.

[0044] The second baffle plate 422 is arranged at the upper end of the first baffle plate 421, and is inclined upward and outward from the first baffle plate, so that the snot falling on the second baffle plate 422 can be blocked and guided by its inclined effect, and the snot falls into the baffle cavity 420 or the suction hole 43, thereby preventing the snot from being sucked into the airway through the suction hole 43.

[0045] The third baffle plate 423 is arranged at the lower end of the first baffle plate 421, and is inclined downward and outward from the first baffle plate, so as to guide the snot after it falls from the guide groove 44 by utilizing its inclined effect, and at the same time isolate the suction hole 43 to prevent the snot from being sucked into the airway from the suction hole 43 during the falling process.

[0046] In order to prevent snot from falling on the third baffle plate 423, in the embodiment of the utility model, please refer to Figure 7 , the size (length, width) of the second baffle plate 422 is larger than the size (length, width) of the third baffle plate 423. The above may also mean that the vertical projection area of ​​the second baffle plate 422 is larger than the vertical projection area of ​​the third baffle plate 423. When the snot falls, it is blocked by the second baffle plate 422 and cannot fall on the third baffle plate 423, so that the snot is prevented from falling directly on the third baffle plate 423 and entering the airway from the suction hole 43.

[0047] In the embodiment of the present utility model, please refer to Figure 6 The first baffle plate 421 is provided with blocking parts 4211 extending outward on both sides. The blocking parts 4211 are provided to further prevent the mucus from being sucked into the air intake hole 43 from both sides of the first baffle plate 421 and entering the airway when flowing through the guide groove 44.

[0048] In the embodiment of the utility model, the two sides of the third baffle plate 423 are respectively provided with guide parts 4231 extending downward. By providing the guide parts 4231, the snot flowing through the guide groove 44 can be further guided, so that the snot can fall stably.

[0049] In the embodiment of the utility model, the height position of the upper end of the first baffle plate 421 is higher than the height position of the upper end of the bracket body 41. This arrangement reduces the blocking effect of the upper end of the bracket body 41 on the snot, further improves the guiding effect of the second baffle plate 421 and the guide groove 44 on the snot, and accelerates the snot to fall. The embodiment of the utility model further illustrates the above effect in combination with the structure of the suction hopper cover 2. The upper opening of the suction hopper cover 2 is a docking column 21 that runs through from top to bottom, which is used for gas conduction and the circulation of snot. Among them, the lower end of the docking column 21 (the part located in the suction bin 10) is set to be aligned with and close to the upper end of the bracket body 41, so that the second baffle plate 422 of the two arched baffles 42 surrounds the lower end of the docking column 21, so that the snot flowing from the docking column 21 to the suction bin falls on the second baffle plate 422 and the guide groove 44, reducing the blocking effect of the upper end of the bracket body 41 on the snot, further improving the diversion effect of the second baffle plate 422 and the guide groove 44 on the snot, and accelerating the diversion and falling of the snot.

[0050] In the embodiment of the utility model, the bracket body 41 is vertically hollowed to form an airway, the lower end of the bracket body 41 is open, and the upper end is closed. The bracket body 41 can be plugged into the upper end of the suction column 11 of the suction warehouse base 1 through the open lower end, so that the bracket body 41 is connected with the suction column 11. Specifically, the outer wall of the suction column 11 is provided with a groove, and the groove is equipped with an O-ring 5. After the open lower end of the bracket body 41 is plugged into the upper end of the suction column 11, the O-ring 5 is in close contact with the inner wall of the bracket body 41.

[0051] In the embodiment of the utility model, the upper end of the bracket body 41 is provided with an arc-shaped chamfered portion 411. By providing the arc-shaped chamfered portion 411 at the upper end of the bracket body 41, the snot falling on the upper end of the bracket body 41 can be accelerated to flow into the guide groove 44 through the arc-shaped chamfered portion 411.

[0052] The bracket body 41 is cylindrical, and in order to facilitate the arrangement of the arcuate baffle plate 42 on the side wall of the cylindrical bracket body 41, the arcuate baffle plate 42 is provided with a connection portion adapted to the arcuate side wall of the bracket body 41, and the air intake hole 43 is provided in the middle of the arrangement position of the bracket body 41 and the arcuate baffle plate 42. In the embodiment of the utility model, the guide bracket is integrally formed to facilitate production and manufacturing.

[0053] In order to increase the sealing performance of the suction hopper cover 2 and the suction hopper base 1 after assembly, an O-ring 6 is installed on the assembly surface. In the embodiment of the utility model, the suction hopper cover 2 and the suction hopper base 1 are connected by threaded assembly. When the two are locked together, the O-ring 6 located on the assembly surface is compressed, thereby achieving the purpose of sealing.

[0054] In the embodiment of the utility model, the suction nozzle 3 is installed at the upper end of the docking column 21 of the suction bin cover 2 (located outside the suction bin 10), and the suction nozzle 3 is connected to the docking column of the suction bin cover 2 through a plug-in detachable assembly. The suction nozzle 3 is used to extend into the nasal cavity and contact with the nasal mucus to achieve the purpose of sucking the nasal mucus, so that the nasal mucus enters the suction bin 10 through the suction nozzle 3 and the docking column 21 of the suction bin cover 2 and falls on the guide bracket 41.

A control component and a suction component are mounted in the housing 200. The suction component is connected to the lower end of the suction column, and the suction component is turned on or off by the control component. When the suction component generates negative pressure, it acts on the suction nozzle through the suction column 11.
