Description

Technical Field

[0001] This utility model relates to medical nebulizers, and more particularly to an anti-tipping nebulizer. Background Technology

[0002] A nebulizer is a medical device that atomizes liquid medication for patients to inhale, and it is widely used in the treatment of respiratory diseases. Currently, common nebulizers on the market mainly consist of a nebulizer cup, a nebulizer head, and a nebulizer unit to provide airflow.

[0003] In existing nebulizers, if the nebulizer cup tilts or tipes over during use, the medication inside will atomize and overflow as foam under the continuous action of the nebulizer head. This not only wastes the medication but also easily causes contamination. This is especially problematic for elderly users and children, as accidental collisions or unstable grips can easily lead to tipping, posing a significant safety hazard. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this invention is to provide an anti-tipping nebulizer.

[0005] To achieve the above objectives, the anti-tipping nebulizer according to an embodiment of the present invention includes:

[0006] An atomizing cup is provided with an upwardly protruding conical airflow nozzle inside the atomizing cup. The conical airflow nozzle is located at the bottom of the atomizing cup, and an atomizing nozzle is provided on one side of the atomizing cup for spraying out atomized liquid.

[0007] Atomizing head, which is located inside the atomizing cup and sleeved on the conical airflow nozzle, is used to atomize the liquid medicine in the atomizing cup to form an atomized liquid;

[0008] A cup lid, which is disposed on the atomizing cup and detachably connected to the atomizing head;

[0009] An airflow seat having a downwardly recessed ball groove and a vent around the ball groove, the airflow seat being adapted to be connected to an atomizing host via an air tube to provide airflow through the atomizing host;

[0010] The atomizing cup has an interface at its bottom that communicates with the conical airflow nozzle. The airflow seat is detachably connected to the interface and defines an airflow chamber. A ball is provided in the airflow chamber. When the atomizing cup is upright, the ball is located in the ball groove under the action of gravity and does not block the vent, so that the airflow provided by the atomizing host can enter the airflow chamber through the vent. When the atomizing cup is tilted, the ball rolls into the conical airflow nozzle to block it.

[0011] The anti-tipping nebulizer provided in this embodiment features an airflow seat and a ball. When the nebulizer cup is in its normal upright position, the ball naturally rests in the groove of the airflow seat under gravity, without affecting the normal airflow function of the vent, ensuring the normal operation of the nebulizer. When the nebulizer cup tilts, the ball automatically rolls under gravity and blocks the conical airflow nozzle, thus blocking the airflow channel. This stops the nebulization function of the nebulizer head, preventing the internal medication from aerating and overflowing, avoiding waste and contamination. This technical solution requires no electronic components or complex mechanisms, has a simple and reliable structure, low manufacturing cost, and is easy to clean and maintain. It effectively solves the tipping and leakage problems existing in current nebulizers, improving product safety and practicality.

[0012] In addition, the anti-tipping nebulizer according to the above embodiments of the present invention may also have the following additional technical features:

[0013] According to one embodiment of the present invention, the atomizing cup includes an upper end, a lower end, and an intermediate portion connecting the upper end and the lower end;

[0014] The diameter of the lower end is larger than the diameter of the upper end, so that when the atomizing cup is tilted, the atomizing cup tilts downward from the lower end to the upper end, thereby causing the bead to automatically roll into the conical airflow nozzle under the action of gravity, so as to close the conical airflow nozzle.

[0015] According to one embodiment of the present invention, the middle part has an annular bladder that protrudes radially outward, and an annular liquid storage groove is formed inside the annular bladder to collect the liquid medicine in the atomizing cup when the atomizing cup is in an inverted state.

[0016] According to one embodiment of the present invention, the maximum diameter of the annular sac portion is smaller than the diameter of the lower end portion but larger than the diameter of the upper end portion.

[0017] According to one embodiment of the present invention, the airflow seat includes:

[0018] The tubing section has an upper end that is detachably connected to the interface section, and a lower end that is adapted to connect to the air tube.

[0019] The partition section is located inside the tube section. The center of the partition section is recessed downward to form the ball groove. The vent hole is located on the partition section and surrounds the ball groove.

[0020] According to one embodiment of the present invention, the lower end of the cup lid has a positioning cylinder, and the lower end of the positioning cylinder has a positioning port;

[0021] The upper end of the atomizing head has a positioning part. When the cup lid is inserted and covers the atomizing cup, the positioning part is engaged with the positioning port so that the atomizing head and the cup lid are circumferentially fixed.

[0022] According to one embodiment of the present invention, the upper end of the tube portion has an internal thread, and the interface portion has an external thread that mates with the internal thread.

[0023] According to one embodiment of the present invention, the bottom of the ball groove is provided with a plurality of micro protrusions, which are used to reduce the contact area between the ball and the ball groove.

[0024] According to one embodiment of the present invention, the conical airflow nozzle is provided with an elastic sealing ring. When the ball blocks the conical airflow nozzle, the elastic sealing ring and the ball form a sealing fit.

[0025] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0059] The anti-tipping atomizing inhaler of this utility model is described in detail below with reference to the accompanying drawings.

[0060] Reference Figures 1 to 4 As shown, the anti-tipping nebulizer provided according to the embodiment of this utility model includes a nebulizer cup 10, a nebulizer head 20, a cup cover 30, and an airflow seat 40.

[0061] Specifically, the nebulizer cup 10 is provided with an upwardly protruding conical airflow nozzle 104, which is located at the bottom of the nebulizer cup 10. An atomizing nozzle H101 is provided on one side of the nebulizer cup 10 for spraying the atomized liquid. Exemplarily, the conical airflow nozzle 104 is located at the center of the nebulizer cup 10, and the conical airflow nozzle 104 is formed into a cone with a diameter that gradually increases from bottom to top. The atomizing nozzle H101 on the side wall of the nebulizer cup 10 can be connected to a mouthpiece or a face mask, which can be selected as needed in specific use. The atomized liquid can be sprayed from the atomizing nozzle, pass through the mouthpiece or face mask, and enter the patient's oral cavity.

[0062] The atomizing head 20 is located inside the atomizing cup 10 and sleeved on the conical airflow nozzle 104, and is used to atomize the liquid medicine in the atomizing cup 10 to form an atomized liquid. Exemplarily, the atomizing head 20 is fixed to the outer circumferential surface of the conical airflow nozzle 104 by a sleeve connection. The atomizing head 20 is used to convert the liquid medicine contained in the atomizing cup 10 into atomized particles under the action of airflow. It is understood that the structure and principle of the atomizing head 20 are known structures in the art. When the atomizing head 20 is sleeved on the conical airflow nozzle 104, a conical gap H20 is formed between the atomizing head 20 and the conical airflow nozzle 104. When compressed air passes through the opening at the top of the conical airflow nozzle 104, a local negative pressure is generated, and the liquid medicine is drawn in from the conical gap H20 and agitated and broken into tiny droplets, thereby forming an atomized liquid.

[0063] The cup lid 30 is placed on the atomizing cup 10 and is detachably connected to the atomizing head 20, for example, by a threaded connection. The cup lid 30 not only prevents the liquid from splashing during use, but also facilitates daily refilling and cleaning.

[0064] The airflow seat 40 has a downwardly recessed ball groove H41 and a vent H40 surrounding the ball groove H41. The airflow seat 40 is adapted to be connected to the atomizing host via an air tube 50 to provide airflow through the atomizing host. When the atomizing host is operating, airflow (e.g., oxygen) can be introduced into the airflow seat 40 and then flow from the vent H40 on the airflow seat 40 into the conical airflow nozzle 104.

[0065] The bottom of the atomizing cup 10 is provided with an interface portion 105 communicating with the conical airflow nozzle 104. The airflow seat 40 is detachably connected to the interface portion 105 and defines an airflow chamber. A ball is provided in the airflow chamber. When the atomizing cup 10 is in an upright state, the ball is located in the ball groove H41 under the action of gravity and does not block the vent H40, so that the airflow provided by the atomizing host can enter the airflow chamber through the vent H40. When the atomizing cup 10 is in a tilted state, the ball rolls into the conical airflow nozzle 104 to block the conical airflow nozzle 104.

[0066] In other words, the airflow seat 40 is detachably connected to the interface portion 105 at the bottom of the atomizing cup 10, while the bead is located within the airflow chamber defined by the conical airflow nozzle 104 and the airflow seat 40. When the atomizing cup 10 is in its normal upright position, the bead naturally falls into the ball groove H41 under the influence of gravity. At this time, the bead will not block the vent H40, allowing the airflow provided by the atomizing host to smoothly enter the airflow chamber through the vent H40 and then enter the atomizing head 20 via the conical airflow nozzle 104, thus achieving normal atomization.

[0067] When the atomizing cup 10 is tilted, the beads will roll out of the ball groove H41 under the action of gravity and automatically roll into the conical airflow nozzle 104. At this time, the beads can tightly seal the conical airflow nozzle 104, blocking the airflow channel, thereby automatically stopping the atomization process and effectively preventing the liquid medicine from continuing to atomize and overflowing in the tilted state.

[0068] It should be noted that, since the atomizing nozzle H101 on the atomizing cup 10 is a tubular structure protruding outwards with a certain length, even when the atomizing cup 10 is tilted on a flat object such as a table, the atomizing nozzle H101 still has a certain height on the flat object, and the liquid medicine in the atomizing cup 10 is not easy to flow out. However, if the atomizing cup 10 is tilted, but the atomizing state inside the atomizing cup 10 is still continuous, the liquid foam generated by the airflow atomization may overflow from the atomizing nozzle H101 under the action of the airflow. Therefore, in this application, the sealing effect of the ball bead is used to block the airflow nozzle 104 when the atomizing cup 10 is tilted, thereby terminating the atomization function and preventing the liquid medicine from overflowing.

[0069] The anti-tipping nebulizer provided in this embodiment of the invention features an airflow seat 40 and a ball. When the nebulizer cup 10 is in its normal upright position, the ball naturally rests in the ball groove H41 of the airflow seat 40 under gravity, without affecting the normal airflow function of the vent H40, thus ensuring the normal operation of the nebulizer. When the nebulizer cup 10 tilts, the ball automatically rolls under gravity and blocks the conical airflow nozzle 104, thereby blocking the airflow channel. This stops the nebulization function of the nebulizer head 20, preventing the internal medication from aerating and overflowing, thus avoiding medication waste and contamination. This technical solution requires no electronic components or complex mechanisms, has a simple and reliable structure, low manufacturing cost, and is easy to clean and maintain. It effectively solves the tipping and leakage problems existing in current nebulizers, improving product safety and practicality.

[0070] In one embodiment of the present invention, the atomizing cup 10 includes an upper end portion 101, a lower end portion 102, and an intermediate portion 103 connecting the upper end portion 101 and the lower end portion 102.

[0071] The diameter of the lower end 102 is larger than the diameter of the upper end 101, so that when the atomizing cup 10 is in a tilted state, the atomizing cup 10 tilts downward from the lower end 102 to the upper end 101, thereby causing the ball to automatically roll into the conical airflow nozzle 104 under the action of gravity, so as to close the conical airflow nozzle 104.

[0072] In this embodiment, the diameter of the lower end 102 is larger than the diameter of the upper end 101, forming a structural design with a larger lower end and a smaller upper end. When the atomizing cup 10 tilts, because the diameter of the lower end 102 is larger than the diameter of the upper end 101, the atomizing cup 10 will naturally form a downward tilting posture from the lower end 102 to the upper end 101. This tilting posture can provide a definite direction for the rolling of the bead, ensuring that the bead rolls quickly and accurately into the conical airflow nozzle 104 under the action of gravity.

[0073] Because the inner cavity of the conical airflow nozzle 104 is conical, with a bottom diameter larger than the top diameter, this structural design allows for a good fit with the ball. When the ball rolls into the conical airflow nozzle 104, it can fit tightly against the inner wall of the conical airflow nozzle 104 under the action of gravity, thereby achieving a reliable sealing effect.

[0074] Through the above structural design, the atomizing cup 10 in this embodiment can always maintain a definite tilt direction when it is tilted. Combined with the rolling characteristics of the beads and the guiding effect of the conical airflow nozzle 104, the automatic sealing of the airflow channel can be achieved more quickly and reliably. At the same time, the segmented structure also facilitates the assembly and maintenance of each component, improving the practicality of the product.

[0075] In some embodiments of this utility model, the middle part 103 has an annular bladder 103a that protrudes radially outward, and an annular liquid storage groove is formed in the annular bladder 103a to collect the liquid medicine in the atomizing cup 10 when the atomizing cup 10 is in a tilted state.

[0076] When the atomizing cup 10 is in its normal upright position, the liquid medication gathers at the bottom of the atomizing cup 10 under gravity, and the annular reservoir is empty, which does not affect the normal function of the atomizing cup 10. However, when the atomizing cup 10 is tilted, the liquid medication inside will flow downwards under gravity. At this time, the annular reservoir acts as a temporary storage container, collecting the flowing liquid medication within it. Because the reservoir is annular, the liquid medication can be effectively intercepted and collected regardless of which direction the atomizing cup 10 is tilted.

[0077] This structural design, combined with the sealing effect of the beads, provides dual protection. When the nebulizer cup 10 is tilted, the beads can promptly cut off the airflow to prevent further atomization, while the annular reservoir collects the existing liquid medication, thus minimizing spillage and waste. The annular reservoir design also facilitates the subsequent return of collected medication to the nebulizer cup 10 for reuse.

[0078] Preferably, the maximum diameter of the annular bladder portion 103a is smaller than the diameter of the lower end portion 102 and larger than the diameter of the upper end portion 101. In this way, while ensuring its function of collecting medicine, it can also ensure that when it is poured, the atomizing cup 10 tilts downward from the direction from the lower end portion 102 to the upper end portion 101, thus ensuring its sealing effect.

[0079] In one embodiment of the present invention, the airflow seat 40 includes a tube portion 401 and a partition portion 402. The upper end of the tube portion 401 is detachably connected to the interface portion 105, and the lower end of the tube portion 401 is adapted to connect to the air pipe 50.

[0080] A partition portion 402 is disposed inside the tube portion 401. The center of the partition portion 402 is recessed downward to form the ball groove H41. The vent hole H40 is disposed on the partition portion 402 and surrounds the ball groove H41.

[0081] In other words, the airflow seat 40 mainly consists of a tube section 401 and a baffle section 402. The baffle section 402 is located inside the tube section 401, and multiple evenly distributed vent holes H40 are provided around the central spherical groove H41 on the baffle section 402. These vent holes H40 ensure uniform airflow. After the airflow enters the tube section 401 from the lower end, it forms multiple uniform airflow streams when passing through the vent holes H40 on the baffle section 402. These airflow streams naturally converge during their upward movement and are finally ejected through the opening at the upper end of the conical airflow nozzle 104.

[0082] By employing the structural design of the tube section 401 and the baffle section 402, not only is effective airflow guidance and uniform distribution achieved, but the reliability of the anti-tipping function is also ensured. At the same time, the detachable structural design improves the product's maintainability, and the overall structure is simple and compact.

[0083] Preferably, the upper end of the tube portion 401 has an internal thread, and the interface portion 105 has an external thread that mates with the internal thread. That is, the airflow seat 40 and the interface portion 105 are threadedly connected, which makes disassembly and assembly simple and convenient, and provides good sealing performance.

[0084] In one embodiment of the present invention, the lower end of the cup lid 30 has a positioning cylinder 301, and the lower end of the positioning cylinder 301 has a positioning port H301.

[0085] The upper end of the atomizing head 20 has a positioning part 201. When the cup lid 30 is inserted and covers the atomizing cup 10, the positioning part 201 is engaged with the positioning port H301 so that the atomizing head 20 and the cup lid 30 are circumferentially fixed.

[0086] During use, when the user installs the cup lid 30 onto the atomizing cup 10, the positioning cylinder 301 of the cup lid 30 will naturally move downwards until its lower positioning port H301 accurately aligns with the upper positioning part 201 of the atomizing head 20. This engagement between the positioning port H301 and the positioning part 201 effectively prevents the atomizing head 20 from rotating circumferentially during use, ensuring that the atomizing head 20 remains in a stable position and avoiding any impact on atomization performance due to shaking. Furthermore, this engagement between the positioning port H301 and the positioning part 201 also facilitates easy assembly and disassembly and maintenance, making cleaning and maintenance more convenient.

[0087] In one embodiment of the present invention, the bottom of the ball groove H41 is provided with a plurality of micro protrusions, which are used to reduce the contact area between the ball and the ball groove H41.

[0088] In this embodiment, by providing multiple micro-protrusions at the bottom of the ball groove H41, the actual contact area between the ball and the bottom of the ball groove H41 can be significantly reduced. This ensures that the ball can remain stably in the ball groove H41 without causing a sticky effect due to an excessively large contact area. The presence of the micro-protrusions means that the ball actually forms point contact with the ball groove H41 through these protrusions, greatly reducing the contact area and minimizing the influence of surface tension.

[0089] In actual use, a small amount of droplets or condensation may appear inside the atomizer. If the bottom of the ball groove H41 is a completely smooth curved surface, this liquid may form a liquid film between the ball and the ball groove H41, increasing the viscosity of the ball. However, with the micro-protrusions, it is more difficult for the liquid to form a continuous liquid film between the protrusions, thus avoiding this situation and further improving the reliability of the tilting and sealing function.

[0090] In one embodiment of this utility model, an elastic sealing ring 106 is provided inside the conical airflow nozzle 104. When the ball blocks the conical airflow nozzle 104, a sealing fit is formed between the elastic sealing ring 106 and the ball.

[0091] When the atomizing cup 10 tilts, the bead rolls into the conical airflow nozzle 104 under gravity. At this time, the bead and the elastic sealing ring 106 of the conical airflow nozzle 104 form a tight seal. Because the elastic sealing ring 106 has good elastic deformation capability, it can deform appropriately according to the pressure of the bead, thereby forming a tighter fit between the bead and the sealing ring. This significantly improves the reliability of the anti-tilt sealing and effectively solves the problem of seal failure that may be caused by manufacturing errors, wear and tear, etc.
