Description

Technical Field

[0001] This utility model relates to the field of atomizers, specifically to a flow stop valve structure with replaceable atomizing plates and a mesh atomizer. Background Technology

[0002] With societal development, people are increasingly valuing their health, and the efficacy of nebulizer therapy is widely recognized by industry professionals and patients with respiratory diseases. As a result, nebulizers are becoming increasingly common in ordinary households. The variety of nebulizers on the market is also growing, with the compact, portable, and easy-to-use mesh nebulizer standing out. These products use a multi-microporous vibrating plate to spray medication into a mist and deliver it into the respiratory tract to achieve therapeutic effects.

[0003] Existing mesh atomizers require frequent replacement of the atomizing plate module to ensure optimal atomization results each time. However, replacing the atomizing plate module when there is medication in the medication cup can cause the medication to leak out, affecting the user experience.

[0004] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0005] The purpose of this invention is to provide a flow-stop valve structure with replaceable atomizing plates and a mesh atomizer, which can effectively prevent the liquid from flowing out when replacing the atomizing plate module, reduce liquid waste and improve the user experience.

[0007] A flow-stop valve structure with a replaceable atomizing plate, wherein the atomizing plate is arranged in the liquid flow channel between the spray nozzle and the liquid cup, and the spray nozzle and the liquid cup are snapped together;

[0008] The flow stop valve is arranged in the liquid flow channel and blocks the liquid flow channel under natural conditions.

[0009] The spray nozzle, which is inserted into the medicine cup, indirectly drives the flow stop valve structure through the atomizing plate to open the medicine flow channel.

[0010] Preferably, the liquid flow channel is arranged in the liquid cup, with its inlet connected to the cup compartment of the liquid cup and its outlet connected to the spray nozzle.

[0011] More preferably, the spray nozzle is engaged with the outlet, and at least one of the engagement surfaces of the two has a limiting groove, and the atomizing plate matches the limiting groove.

[0012] More preferably, the atomizing plate has a support area, and the support area of ​​the atomizing plate placed in the limiting groove corresponds to the flow stop valve structure, so as to indirectly drive the flow stop valve structure.

[0013] More preferably, the check valve structure includes a transmission part and a sealing part, the transmission part being arranged in the liquid flow channel and the sealing part being arranged at the inlet;

[0014] The spray nozzle, which is inserted into the medicine cup, indirectly drives the transmission unit through the atomizing plate, thereby causing the transmission unit to indirectly drive the sealing part to separate from the inlet, so as to open the medicine flow channel.

[0015] Preferably, the sealing part is a flow-stopping ball, the inlet is a slot with a diameter smaller than that of the flow-stopping ball, and a limiting block is provided above the inlet to restrict the upward movement of the flow-stopping ball. The flow-stopping ball seals the inlet under the action of gravity.

[0016] Preferably, the sealing part is an elastic valve plate, which seals the inlet under the action of rebound force.

[0017] More preferably, the transmission part is a rotating push rod, which is rotatably disposed in the liquid flow channel. One end of the rotating push rod corresponds to the atomizing plate, and the other end corresponds to the blocking part. The rotating push rod rotates under the indirect drive of the atomizing plate, pushing the blocking part to separate from the inlet, so as to open the liquid flow channel.

[0052] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0053] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0054] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0055] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0056] Example 1, see appendix Figure 1-7 As shown, this embodiment provides a flow stop valve structure 2 with a replaceable atomizing plate 1. The atomizing plate 1 is arranged in the liquid flow channel 410 between the spray nozzle 3 and the liquid cup 4, and the spray nozzle 3 and the liquid cup 4 are snapped together.

[0057] The flow stop valve structure 2 is arranged in the liquid flow channel 410 and blocks the liquid flow channel 410 under natural conditions.

[0058] The spray nozzle 3, which is inserted into the medicine cup 4, indirectly drives the stop valve structure 2 through the atomizing plate 1 to open the medicine flow channel 410.

[0059] In this embodiment, the spray nozzle 3 and the medicine cup 4 are connected by a slot 420 and a buckle 310. When connected, the atomizing plate 1 can be fixed, making it convenient to replace the atomizing plate 1 and ensuring better atomization effect each time.

[0060] In this embodiment, the liquid flow channel 410 is arranged in the liquid cup 4, with its inlet 411 communicating with the cup chamber of the liquid cup 4 and its outlet 412 formed on the outer wall of the liquid cup 4 and communicating with the spray nozzle 3.

[0061] In this embodiment, the spray nozzle 3 is engaged with the outlet 412, and at least one engaging surface of the two has a limiting groove 440, which fits into the atomizing plate 1. In this embodiment, the limiting groove 440 protrudes outward from the outlet 412 and communicates with the outlet 412. The atomizing plate 1 and the limiting groove 440 are irregularly shaped to axially limit the atomizing plate 1.

[0062] In this embodiment, the atomizing plate 1 has a support region 110 and an atomizing plate microporous region 120. The support region 110 is an outer shell. The support region 110 of the atomizing plate 1, which is placed in the limiting groove 440, corresponds to the stop valve structure 2, thereby indirectly driving the stop valve structure 2. The stop valve structure 2 is driven by the support region 110, and the atomizing plate microporous region 120 is not affected, thus not affecting the atomization effect.

[0063] See appendix Figure 6-7 As shown, the check valve structure 2 includes a transmission part and a sealing part. The transmission part is arranged in the liquid flow channel 410, and the sealing part is arranged at the inlet 411.

[0064] The spray nozzle 3, which is inserted into the liquid cup 4, indirectly drives the transmission unit through the atomizing plate 1, thereby causing the transmission unit to indirectly drive the sealing part to separate from the inlet 411, so as to open the liquid flow channel 410.

[0065] In this embodiment, the blocking part is a flow-stopping ball 210, the inlet 411 is a slot with a diameter smaller than that of the flow-stopping ball 210, the slot is conical, and a limiting block 220 is provided above the inlet 411 to restrict the upward movement of the flow-stopping ball 210. The flow-stopping ball 210 blocks the inlet 411 under the action of gravity.

[0066] In this embodiment, the transmission part is a rotating push rod 230. The rotating push rod 230 is rotatably disposed in the liquid flow channel 410 via a rotating shaft. The rotating push rod 230 is arc-shaped, with one end corresponding to the atomizing plate 1 and the other end corresponding to the sealing part. In its natural state, the rotating push rod 230 is affected by gravity, with one end extending into the limiting groove 440 and the other end located below the sealing part. The rotating push rod 230 rotates under the indirect drive of the atomizing plate 1, pushing the sealing part to separate from the inlet 411, so as to open the liquid flow channel 410.

[0067] See appendix Figure 1-7 As shown, this embodiment also provides a mesh atomizer, including an atomizing plate 1, a spray nozzle 3, a medicine cup 4, and the above-mentioned check valve structure 2.

[0068] The medicine cup 4 is hinged to a lid 5 at its mouth, and a sealing ring 6 is provided at the bottom edge of the lid 5 to seal the lid 5 and the mouth of the cup. The bottom surface of the medicine cup 4 is a slope 430, and the inlet 411 of the medicine flow channel 410 is arranged at the bottom of the slope 430 to ensure smooth flow of medicine and reduce medicine residue.

[0069] When the mesh atomizer is in use, during the process of inserting the spray nozzle 3 into the liquid cup 4, an inward pushing force is applied to the atomizing plate 1. The support area 110 of the atomizing plate 1 pushes the rotating push rod 230 to rotate inward. When the rotating push rod 230 rotates, it pushes the flow-stopping ball 210 out of the conical inlet 411. A gap is created between the flow-stopping ball 210 and the conical inlet 411, thereby opening the liquid flow channel 410. The liquid can then flow to the atomizing plate 1 for atomization.

[0070] When the user needs to replace the atomizing plate 1 during the nebulization process, there is still a lot of medicine in the medicine cup 4. After the user removes the spray nozzle 3, the rotating push rod 230 loses its thrust and rotates outward to reset. At the same time, under the gravity of the flow-stopping ball 210, the rotating push rod 230 is also pushed outward to reset. The flow-stopping ball 210 falls into the conical inlet 411 and contacts the conical surface of the inlet 411, blocking the flow of medicine and thus achieving the purpose of stopping the flow. At this time, removing the spray nozzle 3 and the atomizing plate 1 module will not cause the medicine to flow out, thus avoiding the waste of medicine.

[0071] Example 2, see appendix Figure 8-9 As shown, this embodiment is basically the same as embodiment 1, except that the sealing part is an elastic valve plate 240. The elastic valve plate 240 is installed at the bottom of the medicine cup 4 and covers the inlet 411. The elastic valve plate 240 seals the inlet 411 under the action of the rebound force.

[0072] In this embodiment, the elastic valve plate 240 is used instead of the flow stop ball 210 in embodiment 1. When one end of the rotating push rod 230 is pushed, the other end of the rotating push rod 230 deforms the elastic valve plate 240, creating a gap between it and the inlet 411, opening the liquid flow channel 410, and the liquid flows to the atomizing plate 1 for atomization.

[0073] After removing the spray nozzle 3 and the atomizing plate 1, the rotating push rod 230 loses its thrust. Without external thrust, the elastic valve plate 240 will straighten from its bend due to its own rebound force, thereby blocking the inlet 411 of the liquid flow channel 410 and achieving the purpose of stopping the flow.

[0074] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
