Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a nasal irrigator and nasal irrigation device. Background Technology

[0002] Current nasal irrigators on the market have a design flaw when connected to an external air source for cleaning: the lack of an effective securing mechanism between the air inlet tube and the housing allows it to easily wobble during use due to user operation. This wobble can cause gas leakage, which not only interferes with the normal cleaning process and reduces the cleaning effect, but may also force users to adjust their posture or repeat the operation to compensate for the leakage, thus significantly reducing the user experience. Utility Model Content

[0003] The main purpose of this invention is to provide a nasal irrigator and nasal irrigation device, which aims to solve the problems of shaking and gas leakage during operation caused by the lack of a fixed air inlet pipe, so as to improve the stability and efficiency of the irrigation process and thus improve the user experience.

[0004] To achieve the above objectives, the nasal irrigator proposed in this utility model includes:

[0005] The casing has a cavity and an air inlet;

[0006] A bracket is provided in the cavity to divide the cavity into a raw liquid cavity and an installation cavity, the installation cavity being connected to the air inlet;

[0007] The nasal rinsing device is located in the housing and communicates with the original liquid chamber.

[0008] An air intake assembly includes a support base and an air intake pipe. One end of the air intake pipe is disposed on the support base and extends to the air intake port, and the other end is fixed to the bracket and communicates with the raw liquid chamber. The support base is disposed in the mounting cavity, and both ends of the support base abut against the cavity wall of the mounting cavity.

[0009] In one embodiment, each end of the support base has an arc-shaped protrusion and an arc-shaped recess connecting the arc-shaped protrusion and the air intake pipe, and the arc-shaped protrusion abuts against the cavity wall of the mounting cavity.

[0010] In one embodiment, the intake pipe includes:

[0011] An air intake pipe section is provided in the mounting cavity, with one end of the air intake pipe section provided on the support base and extending to the air intake port, and the other end fixed to the bracket;

[0012] An air guide duct section is provided on the bracket and located in the raw liquid chamber. The bracket is provided with a connecting port, and the air guide duct section is connected to the air inlet duct section through the connecting port.

[0013] In one embodiment, the raw liquid chamber and the mounting chamber are arranged along the height direction of the housing; one end of the air inlet pipe section extends along the height direction of the housing and is fixed to the bracket, the other end of the air inlet pipe section extends along the length direction of the housing to the air inlet, and the air guide pipe section extends along the height direction of the housing.

[0014] In one embodiment, the support includes:

[0015] The support plate is provided with the aforementioned communication port;

[0016] A snap-fit ​​part is provided on the side of the support plate facing the mounting cavity, and the snap-fit ​​part is positioned corresponding to the communication port; the end of the air inlet pipe section away from the air inlet is provided with a snap-fit ​​mating part that snaps into the air inlet pipe section to fix the air inlet pipe section to the support plate and connect it to the air guide pipe section through the communication port.

[0017] In one embodiment, the snap-fit ​​part is a connecting post provided on the support plate, and the connecting post has a through hole;

[0018] The snap-fit ​​part is a snap-fit ​​groove formed in the air intake pipe section. The opening of the snap-fit ​​groove is set facing the support plate. The snap-fit ​​groove snaps into the connecting post to fix the air intake pipe section to the support plate and communicates with the air guide pipe section through the through hole and the connecting port.

[0019] In one embodiment, the support further includes:

[0020] A flow guide is provided on the side of the support plate facing the original liquid chamber. The flow guide is positioned corresponding to the position of the connecting port. The outer periphery of the flow guide is fitted with the air guide pipe section. The flow guide is connected to the air guide pipe section and is connected to the air inlet pipe section through the connecting port.

[0021] In one embodiment, the intake pipe further includes an exhaust pipe section located in the mounting cavity and connected to the intake pipe section, wherein one end of the intake pipe section away from the bracket extends to the intake port and forms an exhaust gap with the intake port.

[0022] The nasal irrigator also includes a trigger, which is located in the housing and is used to cut off the connection between the exhaust pipe section and the exhaust gap when triggered, so that when the gas from the air source is transmitted to the air guide pipe section, it can carry out the cleaning liquid in the original liquid chamber and mix it with the gas to atomize it into water vapor, which is then sprayed out through the nasal irrigator head.

[0023] In one embodiment, the nasal irrigator further includes:

[0024] An elastic element is disposed on the trigger and located in the mounting cavity, the elastic element being disposed toward the exhaust pipe section, and is used to deform to seal the exhaust pipe section when the trigger is triggered.

[0025] This utility model also proposes a nasal irrigation device, comprising:

[0026] Gas source, used to provide gas; and

[0027] As described above, the nasal irrigator has an air inlet tube connected to the air source for receiving gas output from the air source.

[0028] This utility model's nasal irrigator features a housing comprising a cavity and an air inlet. The cavity is divided into a raw liquid cavity and an installation cavity by a support, ensuring effective separation of different functional areas. The nasal irrigation head communicates with the raw liquid cavity, ensuring smooth flow of the cleaning solution. A key feature is the design of its air inlet assembly: this assembly includes a support base and an air inlet pipe. One end of the air inlet pipe is fixed to the support base and extends to the air inlet, while the other end is securely connected to the support and leads to the raw liquid cavity. The support base is located within the installation cavity, with both ends tightly against the cavity wall, achieving a stable fixation. This effectively secures both ends of the air inlet pipe, preventing shaking caused by user operation and thus preventing potential gas leakage. This not only ensures the normal operation of the cleaning process and improves the cleaning effect but also enhances the user experience, eliminating the need for frequent posture adjustments or repetitive operations.

[0039] Current nasal irrigators on the market have a design flaw when connected to an external air source for cleaning: the lack of an effective securing mechanism between the air inlet tube and the housing allows it to easily wobble during use due to user operation. This wobble can cause gas leakage, which not only interferes with the normal cleaning process and reduces the cleaning effect, but may also force users to adjust their posture or repeat the operation to compensate for the leakage, thus significantly reducing the user experience.

[0040] To solve the above problems, this utility model proposes a nasal irrigator 100.

[0041] Please see Figures 1 to 3 In one embodiment of this utility model, the nasal irrigator 100 includes:

[0042] The housing 1 is provided with a cavity 101 and an air inlet 102;

[0043] A bracket 2 is provided in the cavity 101 to divide the cavity 101 into a raw liquid cavity 1011 and an installation cavity 1012, wherein the installation cavity 1012 is connected to the air inlet 102.

[0044] The nasal washing device 3 is located in the housing 1 and is connected to the original liquid chamber 1011;

[0045] The air intake assembly 4 includes a support base 41 and an air intake pipe 42. One end of the air intake pipe 42 is disposed on the support base 41 and extends to the air intake port 102, and the other end is fixed to the bracket 2 and communicates with the raw liquid chamber 1011. The support base 41 is disposed in the mounting cavity 1012, and both ends of the support base 41 abut against the cavity wall of the mounting cavity 1012.

[0046] In this embodiment, the housing 1 is the main outer shell of the nasal irrigator 100, and is provided with a cavity 101 and an air inlet 102 communicating with the cavity 101. The air inlet 102 is used to connect to an external air source to receive the gas output by the external air source.

[0047] The bracket 2 can be installed in the cavity 101 by means of snap-fit, thread, welding, or integral molding, dividing the cavity 101 into a raw liquid cavity 1011 and an installation cavity 1012. The raw liquid cavity 1011 can be located at the top or side of the housing 1 and is used to store cleaning fluid, such as physiological saline. When the raw liquid cavity 1011 is located at the top of the housing 1, the installation cavity 1012 can be located at the bottom of the housing 1; or, when the raw liquid cavity 1011 is located at the first side of the housing 1, the installation cavity 1012 can be located at the second side of the housing 1, wherein the second side is opposite to the first side. The installation cavity 1012 is used to accommodate the air intake assembly 4. The division of the cavity 101 can achieve physical isolation between the cleaning fluid and the air intake assembly 4, avoiding leakage or contamination of the air intake assembly 4 by the cleaning fluid. The air inlet 102 is opened on the cavity wall of the housing 1 corresponding to the installation cavity 1012 and communicates with the installation cavity 1012, serving as the access point for an external air source. The external air source can be a manually squeezed airbag, or it can be breathing air, etc., and there are no specific restrictions here.

[0048] The nasal irrigation nozzle 3 can be a cone-shaped or trumpet-shaped nozzle. One end of the nasal irrigation nozzle 3 is installed in the housing 1 and connected to the original liquid chamber 1011. The other end of the nasal irrigation nozzle 3 can be provided with a nasal irrigation opening. The inner wall of the nasal irrigation opening can be provided with a serrated or vortex structure to further atomize the liquid after the gas and cleaning liquid are mixed into fine particles, thereby improving the atomization effect on the nasal cavity.

[0049] The air intake assembly 4 may include a support base 41 and an air intake pipe 42. The air intake pipe 42 may be made of a flexible or semi-rigid material to ensure smooth airflow. One end of the air intake pipe 42 is fixed to the support base 41 and extends to the air inlet 102 of the housing 1 for connection and communication with an external air source. The other end of the air intake pipe 42 may be fixed to the bracket 2 by means of snap-fit, thread, welding, or integral molding, and communicates with the original liquid chamber 1011. The support base 41 may be made of a rigid material to improve the stability of supporting the air intake pipe 42. The support is installed in the mounting cavity 1012, with both ends abutting against the two side walls of the mounting cavity 1012. That is, one end of the air intake pipe 42 is directly fixed to the bracket 2, and the other end of the air intake pipe 42 is fixed to the cavity wall of the mounting cavity 1012 via the support base 41. In this way, when the user connects the air intake pipe 42 to the external air source through the air inlet 102, it can prevent the interface between the air intake pipe 42 and the external air source from loosening due to shaking, thereby reducing gas leakage.

[0050] The nasal irrigator 100 of this utility model features a housing 1 comprising a cavity 101 and an air inlet 102. The cavity 101 is divided into a raw liquid cavity 1011 and a mounting cavity 1012 by a support 2, ensuring effective separation of different functional areas. The nasal irrigation head 3 communicates with the raw liquid cavity 1011, ensuring smooth outflow of the cleaning solution. A key feature is the design of its air intake assembly 4: this assembly includes a support base 41 and an air intake pipe 42. One end of the air intake pipe 42 is fixed to the support base 41 and extends to the air inlet 102, while the other end is securely connected to the support 2 and leads to the raw liquid cavity 1011. The support base 41 is located within the mounting cavity 1012, with both ends tightly abutting the cavity wall of the mounting cavity 1012, thus achieving a stable fixation. This effectively secures both ends of the air intake pipe 42, preventing shaking caused by user operation and thus preventing potential gas leakage. This not only ensures the normal progress of the cleaning process and improves the cleaning effect, but also enhances the user experience, eliminating the need for frequent adjustments to posture or repetitive operations.

[0051] Please see Figures 1 to 3 In one embodiment of the present invention, each end of the support base 41 has an arc-shaped protrusion 411 and an arc-shaped recess 412 connecting the arc-shaped protrusion 411 and the air intake pipe 42. The arc-shaped protrusion 411 abuts against the cavity wall of the mounting cavity 1012.

[0052] In this embodiment, the two ends of the support base 41 extend towards the cavity wall of the mounting cavity 1012 with arc-shaped protrusions 411 and arc-shaped protrusions 411. When the support base 41 contacts the cavity wall of the mounting cavity 1012, point or line contact can be achieved through the arc-shaped protrusions 411, rather than planar contact. This contact method can increase friction, which helps to more firmly fix the position of the support base 41 and prevent it from sliding in the mounting cavity 1012. Furthermore, since the arc-shaped protrusions 411 can tightly abut against the cavity wall of the mounting cavity 1012, it can not only ensure the stability and positioning accuracy of the support base 41, but also effectively disperse the pressure acting on the support base 41, avoiding damage caused by excessive local stress. The arc-shaped recessed section 412 is used to connect the arc-shaped protrusions 411 and the air intake pipe 42. In this way, it not only helps to enhance the structural integrity of the support base 41, but also absorbs or buffers the impact force on the air intake pipe 42 to a certain extent, reducing the risk of damage caused by accidental collisions or improper operation.

[0053] Please see Figures 1 to 3 In one embodiment of this utility model, the air intake pipe 42 includes:

[0054] An air intake pipe section 421 is provided in the mounting cavity 1012. One end of the air intake pipe section 421 is provided in the support base 41 and extends to the air intake port 102, and the other end is fixed to the bracket 2.

[0055] The air guide duct section 422 is provided on the bracket 2 and located in the raw liquid chamber 1011. The bracket 2 is provided with a connecting port 201. The air guide duct section 422 is connected to the air inlet duct section 421 through the connecting port 201.

[0056] In this embodiment, the air inlet pipe section 421 is located inside the mounting cavity 1012. One end of it is set on the support base 41 and extends to the air inlet 102, while the other end is fixed to the bracket 2. This ensures that the gas entering from the external air source can be smoothly introduced into the nasal irrigator 100 through the air inlet pipe section 421. At the same time, the stable connection between it and the support base 41 and the bracket 2 reduces the risk of leakage during gas transmission.

[0057] The air guide duct section 422 is mounted on the bracket 2 and located in the raw liquid chamber 1011. The bracket 2 has a connecting port 201, allowing the air guide duct section 422 to connect with the air inlet duct section 421. This design aims to guide the gas accurately into the raw liquid chamber 1011, where it mixes with the cleaning fluid and atomizes into water vapor, which is then sprayed out through the nasal irrigation head 3 to clean the nasal cavity. In other words, by setting up the air guide duct section 422, the gas flow path is optimized, ensuring that the gas can reach the raw liquid chamber 1011 efficiently and directly, improving cleaning efficiency and effectiveness. Furthermore, by placing the air guide duct section 422 inside the raw liquid chamber 1011 and connecting it to the air inlet duct section 421 through the connecting port 201 on the bracket 2, the sealing of the nasal irrigator 100 is enhanced, reducing the possibility of gas leakage.

[0058] Please see Figures 1 to 3 In one embodiment of this utility model, the original liquid chamber 1011 and the mounting chamber 1012 are arranged along the height direction of the housing 1; one end of the air inlet pipe section 421 extends along the height direction of the housing 1 and is fixed to the bracket 2, the other end of the air inlet pipe section 421 extends along the length direction of the housing 1 to the air inlet 102, and the air guide pipe section 422 extends along the height direction of the housing 1.

[0059] In this embodiment, the raw liquid chamber 1011 and the mounting chamber 1012 are arranged along the height direction (i.e., vertical direction) of the housing 1, which means that the raw liquid chamber 1011 and the mounting chamber 1012 are stacked vertically, specifically, the raw liquid chamber 1011 is located above the mounting chamber 1012. One end of the air inlet pipe section 421 extends along the height direction of the housing 1 and is fixed to the bracket 2, which ensures a stable connection between the raw liquid chamber 1011 and the mounting chamber 1012, and facilitates the introduction of gas into the raw liquid chamber 1011. The other end of the air inlet pipe section 421 extends along the length direction (i.e., front-to-back direction) of the housing 1 to the air inlet 102, ensuring that the external air source can be smoothly connected to the air intake assembly 4. The air guide pipe section 422 also extends along the height direction of the housing 1 and is connected to the air inlet pipe section 421 through the connecting port 201 on the bracket 2, guiding the gas into the raw liquid chamber 1011 for cleaning operation.

[0060] In other words, by arranging the original liquid chamber 1011 and the mounting chamber 1012 along the height direction and adjusting the layout of the air inlet pipe section 421 and the air duct section 422 accordingly, this embodiment can maximize the space utilization efficiency of the housing 1 without increasing the volume of the nasal irrigator 100, making the entire nasal irrigator 100 more compact.

[0061] Please see Figures 1 to 3 In one embodiment of this utility model, the bracket 2 includes:

[0062] The support plate 21 is provided with the communication port 201;

[0063] A snap-fit ​​part 22 is provided on the side of the support plate 21 facing the mounting cavity 1012, and the snap-fit ​​part 22 is positioned corresponding to the position of the connecting port 201; the end of the air intake pipe section 421 away from the air intake port 102 is provided with a snap-fit ​​mating part 4211, and the snap-fit ​​mating part 4211 engages with the snap-fit ​​part 22 to fix the air intake pipe section 421 to the support plate 21 and connect it to the air guide pipe section 422 via the connecting port 201.

[0064] In this embodiment, the support plate 21 is part of the bracket 2 and has a communication port 201 for gas flow between the air duct section 422 and the air inlet section 421. A snap-fit ​​part 22 is located on the side of the support plate 21 facing the mounting cavity 1012, and its position corresponds to the communication port 201. The snap-fit ​​part 22 is designed to engage with a snap-fit ​​mating part 4211 on the air inlet section 421. The snap-fit ​​mating part 4211 is a protruding portion at the end of the air inlet section 421 away from the air inlet 102. This portion is designed to engage with the snap-fit ​​part 22, thereby firmly fixing the air inlet section 421 to the support plate 21 and ensuring that it can communicate with the air duct section 422 via the communication port 201. The nasal irrigator 100 is secured using a snap-fit ​​method, eliminating the need for additional tools or complex procedures during assembly. This simplifies the manufacturing process, reduces costs, and facilitates easier repair or replacement of the air intake section 421 if damaged, without requiring the replacement of the entire air intake assembly 4, thus improving the maintainability of the nasal irrigator 100. Furthermore, the snap-fit ​​mechanism not only provides mechanical fixation but also ensures a good seal at the interface between the air intake section 421 and the air duct section 422, reducing the possibility of gas leakage and ensuring proper cleaning operation.

[0065] Please see Figures 1 to 3 In one embodiment of the present invention, the snap-fit ​​part 22 is a connecting post provided on the support plate 21, and the connecting post has a through hole 202.

[0066] The snap-fit ​​part 4211 is a snap-fit ​​groove opened on the air intake pipe section 421. The opening of the snap-fit ​​groove is set facing the support plate 21. The snap-fit ​​groove snaps into the connecting post to fix the air intake pipe section 421 to the support plate 21 and communicates with the air guide pipe section 422 through the through hole 202 and the connecting port 201.

[0067] In this embodiment, the snap-fit ​​part 22 is specifically a connecting post provided on the support plate 21. This connecting post has a through hole 202, which allows gas to flow smoothly from the inlet pipe section 421 to the guide pipe section 422. The snap-fit ​​mating part 4211 is a snap-fit ​​groove provided on the inlet pipe section 421, with its opening facing the support plate 21. The snap-fit ​​groove is designed to precisely match the connecting post, thereby achieving a secure snap-fit ​​mating. During assembly, the snap-fit ​​groove on the inlet pipe section 421 engages with the connecting post on the support plate 21, fixing the inlet pipe section 421 to the support plate 21. Through the through hole 202 on the connecting post and the connecting opening 201 on the support plate 21, an effective gas flow path is formed between the inlet pipe section 421 and the guide pipe section 422. Gas can be efficiently and unobstructedly transmitted from the inlet pipe section 421 to the guide pipe section 422, improving gas transmission efficiency and reducing energy loss.

[0068] Please see Figures 1 to 3 In one embodiment of this utility model, the bracket 2 further includes:

[0069] A flow guide 23 is provided on the side of the support plate 21 facing the original liquid chamber 1011. The flow guide 23 is positioned corresponding to the position of the communication port 201. The outer periphery of the flow guide 23 is fitted with the air guide pipe section 422. The flow guide 23 is connected to the air guide pipe section 422 and is connected to the air inlet pipe section 421 via the communication port 201.

[0070] In this embodiment, the guide section 23 is located on the side of the support plate 21 facing the original liquid chamber 1011, and its position corresponds to the communication port 201. The purpose of the guide section 23 is to guide the gas smoothly from the air inlet section 421 to the air guide section 422. The air guide section 422 is sleeved on the outer periphery of the guide section 23, which means that the air guide section 422 is wrapped around the outside of the guide section 23. This design allows the gas to smoothly transition from the air inlet section 421 to the air guide section 422, reducing the resistance and turbulence of the gas during transmission and improving the gas transmission efficiency. Furthermore, this cooperation between the guide section 23 and the air guide section 422 simplifies the assembly process of the nasal irrigator 100, allowing the various components of the nasal irrigator 100 to be assembled more quickly and accurately, reducing manufacturing costs and improving production efficiency.

[0071] Please see Figures 1 to 3 In one embodiment of the present invention, the air intake pipe 42 further includes an exhaust pipe section 423, the exhaust pipe section 423 is located in the mounting cavity 1012 and is connected to the air intake pipe section 421, and the end of the air intake pipe section 421 away from the bracket 2 extends to the air intake port 102 and forms an exhaust gap 103 with the air intake port 102.

[0072] The nasal irrigator 100 also includes a trigger 5, which is disposed in the housing 1 and is used to cut off the connection between the exhaust pipe section 423 and the exhaust gap 103 when triggered, so that when the gas from the air source is transmitted to the air guide pipe section 422, the cleaning liquid in the original liquid chamber 1011 can be carried out and mixed with the gas to atomize into water vapor and then sprayed out through the nasal irrigator head 3.

[0073] In this embodiment, the air intake pipe 42 further includes an exhaust pipe section 423, which is located within the mounting cavity 1012 and communicates with the air intake pipe section 421. The end of the air intake pipe section 421 furthest from the bracket 2 extends to the air inlet 102, forming an exhaust gap 103 therebetween, allowing gas to escape. The nasal irrigator 100 is also equipped with a trigger 5, which is mounted on the housing 1. When the trigger 5 is activated, it can cut off the communication path between the exhaust pipe section 423 and the exhaust gap 103. After the trigger 5 cuts off the communication between the exhaust pipe section 423 and the exhaust gap 103, the gas from the air source will be directly transmitted to the air guide pipe section 422. At this point, the gas effectively carries out the cleaning fluid from the original liquid chamber 1011, mixes with the gas, and atomizes into water vapor. This vapor is then sprayed out through the nasal spray nozzle 3 to clean the nasal cavity. After cleaning is complete, the gas supply stops, the trigger 5 is no longer triggered, and the exhaust gap 103 and exhaust pipe section 423 re-establish communication. The gas in the air guide pipe section 422 and air inlet pipe section 421 can be discharged to the external environment through the exhaust gap 103 and air inlet 102, respectively. The trigger 5 allows users to more precisely control the cleaning process, reduce unnecessary gas waste, and ensure that each cleaning achieves the best results, thus improving the user experience.

[0074] Please see Figures 1 to 3 In one embodiment of this utility model, the nasal irrigator 100 further includes:

[0075] An elastic element 6 is disposed on the trigger element 5 and located in the mounting cavity 1012. The elastic element 6 is disposed toward the exhaust pipe section 423 and is used to deform when the trigger element 5 is triggered to seal the exhaust pipe section 423.

[0076] In this embodiment, the trigger 5 is provided with an elastic element 6, which is placed in the mounting cavity 1012, with the elastic element 6 facing the exhaust pipe section 423. When the trigger 5 is not triggered, the elastic element 6 remains in its initial state; once the trigger 5 is subjected to external operation (such as a user pressing it), the elastic element 6 deforms, thereby sealing the exhaust pipe section 423. This means that when it is necessary to cut off the connection between the exhaust pipe section 423 and the exhaust gap 103, the action of the trigger 5 can make the elastic element 6 tightly fit or press against the exhaust pipe section 423, achieving a sealing effect. This sealing method based on the elastic element 6 is relatively simple and effective, achieving good sealing performance without complex mechanical devices, which helps to simplify the product design of the nasal irrigator 100, and also facilitates production and assembly.

[0077] This utility model also proposes a nasal irrigation device, which includes an air source and a nasal irrigator 100. The specific structure of the nasal irrigator 100 is as described in the above embodiments. Since this nasal irrigation device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0078] The air source can be a manual air source, such as a squeeze-type airbag, or an electric air source, such as a miniature air pump; no specific restrictions are imposed here. In practical applications, when the user needs the nasal irrigator 100, they can press the trigger 5. The trigger 5 is activated, which cuts off the connection between the exhaust gap 103 and the exhaust pipe section 423, allowing the gas output from the air source to directly enter the air duct section 422 through the air inlet section 421. This carries out the cleaning liquid in the original liquid chamber 1011, mixes it with the gas, and atomizes it into water vapor. Finally, the water vapor is sprayed out through the nasal irrigator head 3 to clean the nasal cavity. After the cleaning is completed, the air source stops supplying gas, the trigger 5 is no longer triggered, and the exhaust gap 103 and the exhaust pipe section 423 are reconnected. The gas in the air duct section 422 and the air inlet section 421 can be discharged to the external environment through the exhaust gap 103 and the air inlet 102, respectively. Since both ends of the air intake pipe section 421 in this invention can be effectively fixed, shaking caused by user operation can be avoided, thus preventing potential gas leakage. This not only ensures the normal progress of the cleaning process and improves the cleaning effect, but also enhances the user experience, eliminating the need for frequent posture adjustments or repetitive operations.

[0079] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
