Description

Technical Field

[0001] This application relates to the technical field of atomization products, and particularly to an atomization device. Background Art

[0002] A humidifier is a household appliance that increases the humidity of a room. A humidifier can humidify a designated room or be connected to a boiler or central air conditioning system to humidify an entire building.

[0003] In the related art, a float structure is widely used in humidifiers to control the water level in the cavity of the humidifier. In most humidifiers, the float structure is generally installed at the position of the water outlet in the humidifier. One end of it is fixed and the other end is free. The float structure uses the lever principle or the magnetic attraction principle to open or close the water outlet. Due to the relatively narrow space at the water outlet in the humidifier, the above float structure has great installation difficulty at the water outlet, which affects the overall assembly efficiency of the humidifier and is not conducive to the large-scale production of humidifier products. Summary of the Utility Model

[0004] This application aims to solve at least one of the technical problems existing in the prior art. For this reason, this application provides an atomization device, which enables the float valve to have the function of conducting and blocking the liquid storage cavity and the atomization cavity inside the box body, and at the same time can effectively reduce the installation difficulty of the float valve in the box body and improve the overall assembly efficiency of the atomization device.

[0005] This application provides an atomization device, including:

[0006] A box body, inside which there are formed a liquid storage cavity, a liquid passing channel and an atomization cavity distributed at intervals, and the liquid storage cavity is communicated with the atomization cavity through the liquid passing channel;

[0007] A float valve, limited in the atomization cavity, capable of rising and falling relative to the atomization cavity according to the liquid level change in the atomization cavity to block or open the liquid passing channel;

[0008] Wherein, the float valve blocks the liquid passing channel when the liquid level in the atomization cavity is higher than or equal to a first preset liquid level, and partially or completely opens the liquid passing channel when the liquid level in the atomization cavity is lower than the first preset liquid level.

[0009] According to the atomization device of this application, it has at least the following beneficial effects:

[0010] In the atomizing device according to the embodiment of the present application, by limiting the float valve in the atomizing chamber, the float valve only has the degree of freedom of lifting and lowering in the atomizing chamber. At the same time, the liquid level in the atomizing chamber drives the float valve to perform a single lifting and lowering movement in the atomizing chamber, dynamically conducting or blocking the connection between the atomizing chamber and the liquid storage chamber, so that the liquid storage chamber can dynamically supplement liquid into the atomizing chamber based on the liquid level change in the atomizing chamber, thereby keeping the liquid level in the atomizing chamber within a preset liquid level range all the time, ensuring the normal supply of the liquid in the atomizing chamber, avoiding the atomizing function failure caused by the lack of liquid in the atomizing chamber, and enabling the atomizing device to operate stably.

[0011] Compared with the existing float structures that use the lever principle or the magnetic attraction principle to conduct or block the connection between the atomizing chamber and the liquid storage chamber, in the atomizing device according to the embodiment of the present application, the assembly of the float valve only needs to meet the requirement that it has a single degree of freedom of lifting and lowering in the atomizing chamber. While enabling the float valve to have the function of conducting and blocking the liquid storage chamber and the atomizing chamber inside the box body, it can effectively reduce the installation difficulty of the float valve in the box body and improve the overall assembly efficiency of the atomizing device.

[0012] In some embodiments, when the liquid level in the atomizing chamber is higher than or equal to the first preset liquid level, the float valve is in interference fit with the end of the liquid passing channel that communicates with the atomizing chamber.

[0013] With such a setting, the gap between the float valve and the port of the liquid passing channel is eliminated, and the float valve completely blocks the liquid passing channel.

[0014] In some embodiments, the float valve includes a gravity part and a blocking part connected to the top of the gravity part. The blocking part vertically penetrates the liquid passing channel, and a stop surface for blocking or opening the liquid passing channel is formed at the connection between the blocking part and the gravity part.

[0015] With such a setting, there is no need to set up an additional transmission structure or driving structure to realize dynamically conducting or blocking the connection between the atomizing chamber and the liquid storage chamber, so that the liquid level in the atomizing chamber can be maintained within a preset liquid level range all the time, ensuring the normal supply of the liquid in the atomizing chamber, avoiding the atomizing function failure caused by the lack of liquid in the atomizing chamber, and enabling the atomizing device to operate stably.

[0016] In some embodiments, the liquid passing channel includes a connected horizontal section and a vertical section. The horizontal section communicates with the liquid storage chamber, and the vertical section communicates with the atomizing chamber. The blocking part vertically penetrates the vertical section and forms a first liquid passing gap with the vertical section. The vertical projection of the vertical section relative to the stop surface is within the stop surface.

[0017] With such a setting, it is avoided that the blocking part forms a structural interference with the vertical section when penetrating into the vertical section.

[0018] In some embodiments, a flared portion is formed at the bottom end of the liquid passage.

[0019] With such a setting, the flared portion can provide positioning and guidance for the plugging portion of the float valve to vertically penetrate into or disengage from the liquid passage, and also reduces the risk of structural interference between the plugging portion of the float valve and the liquid passage.

[0020] In some embodiments, the gravity portion is configured as a spherical structure, and the plugging portion is configured as a rod-shaped structure.

[0021] With such a setting, while forming a stop surface between the gravity portion and the plugging portion, it is convenient for the plugging portion to be vertically disposed in the vertical section of the liquid passage. In addition, when the rod-shaped plugging portion is inserted into the liquid passage and is in a position state where the liquid passage is not completely plugged, when the liquid in the liquid passage flows into the atomization chamber, the liquid will flow along the rod wall instead of directly flushing out from the liquid passage, which reduces the noise generated when the liquid in the liquid passage flows into the atomization chamber to a certain extent.

[0022] In some embodiments, the gravity portion and the plugging portion are configured as an integrally formed structure.

[0023] With such a setting, the forming process of the float valve as a whole can be reduced, the forming efficiency of the float valve can be improved, which is beneficial to the large-scale production of the atomization device.

[0024] In some embodiments, a float chamber communicating with the atomization chamber is formed at the bottom of the atomization chamber. The liquid storage chamber communicates with the float chamber through the liquid passage. The float valve is disposed in the float chamber in a liftable manner, and the float chamber can limit the float valve in the length direction and width direction of the float valve.

[0025] With such a setting, the float valve only has the degree of freedom of movement of lifting in the atomization chamber, avoiding the problem that the float valve is offset to both sides under the action of the buoyancy of the liquid in the atomization chamber or the float chamber or the liquid impact force at the port of the liquid passage, resulting in difficulty in aligning with the liquid passage and plugging the liquid passage, and ensuring the stability of the float valve to plug or open the liquid passage through the lifting action.

[0026] In some embodiments, a plurality of retaining ribs are provided at the bottom of the box body. All the retaining ribs and the inner wall of the box body surround to form the float chamber, and a second liquid passage gap communicating with the atomization chamber is formed between adjacent two retaining ribs.

[0027] With such a setting, the function of limiting the float valve in the length direction and width direction of the float valve is realized, so that the float valve can only make a single lifting motion in the height direction, ensuring the stability of the float valve to plug or open the liquid passage through the lifting action.

[0028] Meanwhile, the second liquid passing gap formed between two adjacent said retaining ribs ensures that there is a sufficiently large communication gap between the float chamber and the atomization chamber, ensuring that the liquid in the liquid storage chamber can freely flow into the atomization chamber in the conducting state of the liquid passing channel, so that the liquid in the atomization chamber can be normally supplied.

[0029] In some embodiments, the atomization device further includes an atomization assembly, and the atomization assembly is used to atomize the liquid in the atomization chamber and discharge the mist.

[0030] With such a setting, the normal humidifying effect of the atomization device on the environment is ensured.

[0048] A humidifier is a household appliance that increases the humidity of a room. The humidifier can humidify a designated room or be connected to a boiler or a central air conditioning system to humidify an entire building.

[0049] In the related art, a float structure is widely used in a humidifier to control the water level in the cavity of the humidifier. In most humidifiers, the float structure is generally installed at the position of the water outlet in the humidifier. One end of it is fixed and the other end is free. The float structure uses the lever principle or the magnetic attraction principle to open or close the water outlet. Since the space at the water outlet in the humidifier is relatively narrow, the above-mentioned float structure has a large installation difficulty at the water outlet, which affects the overall assembly efficiency of the humidifier and is not conducive to the large-scale production of humidifier products.

[0050] Based on the problem that the float structure of the existing humidifier has a large installation difficulty at the water outlet and affects the overall assembly efficiency of the humidifier, one or more embodiments of this application provide an atomization device. Through the cooperation of the liquid storage cavity, the liquid passing channel, the atomization cavity and the float valve limitedly arranged in the atomization cavity in the box body, compared with the existing float structure that uses the lever principle or the magnetic attraction principle to conduct or block the connection between the atomization cavity and the liquid storage cavity, the assembly of the float valve only needs to meet the requirement that it has a single degree of freedom of lifting and lowering in the atomization cavity. While enabling the float valve to have the function of conducting and blocking the liquid storage cavity and the atomization cavity inside the box body, it can effectively reduce the installation difficulty of the float valve in the box body and improve the overall assembly efficiency of the atomization device.

[0051] See Figure 1 、 Figure 2 and Figure 3 In an embodiment of the present application, an atomizing device is provided. The atomizing device includes a box body 100 and a float valve 200.

[0052] A liquid storage cavity 110, a liquid passing channel 130 and an atomizing cavity 120 are formed inside the box body 100 at intervals. The liquid storage cavity 110 communicates with the atomizing cavity 120 through the liquid passing channel 130.

[0053] The float valve 200 is limitedly arranged in the atomizing cavity 120. The float valve 200 can rise and fall relative to the atomizing cavity 120 according to the liquid level change in the atomizing cavity 120 to block or open the liquid passing channel 130.

[0054] Among them, the float valve 200 blocks the liquid passing channel 130 when the liquid level in the atomizing cavity 120 is higher than or equal to a first preset liquid level, and partially or completely opens the liquid passing channel 130 when the liquid level in the atomizing cavity 120 is lower than the first preset liquid level.

[0055] In an embodiment of the present application, the box body 100 can be, but is not limited to, in the shape of a cube, a cylinder, a sphere, etc. In the box body 100, the liquid storage cavity 110 is used to store liquid substances, and the liquid substances can be humidifying liquids such as pure water and distilled water for atomization treatment by the atomizing device.

[0056] The atomizing cavity 120 and the liquid storage cavity 110 are distributed at intervals. It should be noted that the atomizing device further includes an atomizing component 300. The atomizing component 300 is detachably arranged in the atomizing cavity 120, which is convenient for disassembly and replacement of the atomizing component 300. The atomizing component 300 is used to atomize the liquid in the atomizing cavity 120 and discharge the mist. Exemplarily, the atomizing component 300 adopts an atomizing module used in a conventional atomizing device. The atomizing component 300 can atomize the liquid in the atomizing cavity 120 into tiny water droplets by using ultrasonic waves or a vibrating membrane, and release the tiny water droplets into the environment to increase the environmental humidity.

[0057] In the box body 100, the liquid passing channel 130 can be formed at a position close to the bottom of the box body 100, and the float valve 200 is arranged below the liquid passing channel 130.

[0058] In addition, it should be noted that in the embodiments of the present application, the box body 100 may be provided with limiting structures such as buckles, limiting notch openings, and limiting cavities. The float valve 200 can be limited and arranged in the atomization cavity 120 of the box body 100 through corresponding limiting structures such as buckles, limiting grooves, and limiting cavities. By limiting the float valve 200 in the atomization cavity 120, the float valve 200 only has the freedom to move along the height direction Z of the atomization cavity 120, that is, only has the freedom of lifting and lowering, avoiding the problem that the float valve 200 is offset to both sides due to the buoyancy of the liquid in the atomization cavity 120 or the impact force of the liquid in the liquid passing channel 130, resulting in difficulty in aligning with the liquid passing channel 130 and blocking the liquid passing channel 130.

[0059] It should be noted that in the present application, the float valve 200 adaptively rises and falls in the atomization cavity 120 according to the dynamic change of the liquid level in the atomization cavity 120 to block or open the liquid passing channel 130. When the float valve 200 blocks the liquid passing channel 130, the liquid in the liquid storage cavity 110 cannot be input into the atomization cavity 120 through the liquid passing channel 130; when the float valve 200 opens the liquid passing channel 130, the liquid in the liquid storage cavity 110 can normally be input into the atomization cavity 120 through the liquid passing channel 130 for atomization consumption by the atomization assembly 300.

[0060] See Figure 4 and Figure 5 , in Figure 4 and Figure 5 , the float valve 200 is in a state of blocking the liquid passing channel 130, that is, when the liquid level in the atomization cavity 120 is higher than or equal to the first preset liquid level, at this time, the liquid level in the atomization cavity 120 is relatively high, and the buoyancy of the liquid in the atomization cavity 120 acting on the float valve 200 in the atomization cavity 120 is greater than the gravity of the float valve 200 itself, causing the float valve 200 to float relative to the bottom of the atomization cavity 120 to a position where the liquid passing channel 130 is completely blocked.

[0061] See Figure 2 and Figure 3 , in Figure 2 and Figure 3 , the float valve 200 is in a state of partially opening the liquid passing channel 130, that is, when the liquid level in the atomization cavity 120 is lower than the first preset liquid level, at this time, the liquid level in the atomization cavity 120 is relatively low, and the buoyancy of the liquid in the atomization cavity 120 acting on the float valve 200 in the atomization cavity 120 is less than the gravity of the float valve 200 itself. The float valve 200 descends to a position where the buoyancy received is equal to the gravity of the float valve 200 itself, thereby partially opening the liquid passing channel 130.

[0062] When the liquid level in the atomization chamber 120 is lower than the second preset liquid level, the liquid level in the atomization chamber 120 is very low at this time, and the float valve 200 directly sinks to the bottom of the atomization chamber 120 due to its own gravity, thus completely opening the liquid passing channel 130. It can be understood that the second preset liquid level is lower than the first preset liquid level.

[0063] It should be understood that, referring to Figure 2 and Figure 3 , when the liquid level in the atomization chamber 120 is between the second preset liquid level and the first preset liquid level, the float valve 200 blocks part of the liquid passing channel 130, that is, the float valve 200 does not completely block the liquid passing channel 130 at this time, and there is a liquid passing gap for liquid to flow between the float valve 200 and the liquid passing channel 130. At this time, the liquid in the liquid storage chamber 110 can slowly flow into the atomization chamber 120 until the liquid level in the atomization chamber 120 reaches the first preset liquid level.

[0064] In the atomization device of the present application, the first preset liquid level and the second preset liquid level can be adaptively set based on the gravity of the float valve 200 and previous experimental debugging, and are not specifically limited.

[0065] It is not difficult to understand that in the atomization device of the embodiment of the present application, by limiting the float valve 200 in the atomization chamber 120, the float valve 200 only has the degree of freedom of lifting and lowering in the atomization chamber 120. At the same time, the float valve 200 is driven by the height of the liquid level in the atomization chamber 120 to make a single lifting and lowering movement in the atomization chamber 120, dynamically conducting or blocking the connection between the atomization chamber 120 and the liquid storage chamber 110, so that the liquid storage chamber 110 can dynamically supplement liquid into the atomization chamber 120 based on the liquid level change of the atomization chamber 120, so that the liquid level in the atomization chamber 120 is always maintained within a preset liquid level range, ensuring the normal supply of the liquid in the atomization chamber 120, avoiding the atomization function failure caused by the lack of liquid in the atomization chamber 120, and enabling the atomization device to operate stably.

[0066] Compared with the existing float structure that uses the lever principle or the magnetic attraction principle to conduct or block the connection between the atomization chamber 120 and the liquid storage chamber 110, in the atomization device of the embodiment of the present application, the assembly of the float valve 200 only needs to meet the requirement that it has a single degree of freedom of lifting and lowering in the atomization chamber 120. While enabling the float valve to have the function of conducting and blocking the liquid storage chamber and the atomization chamber inside the box body, it can effectively reduce the installation difficulty of the float valve in the box body and improve the overall assembly efficiency of the atomization device.

[0067] In some embodiments of the present application, referring to Figure 4 and Figure 5 , when the liquid level in the atomization chamber 120 is higher than or equal to the first preset liquid level, the float valve 200 is in interference fit with the end of the liquid passing channel 130 communicating with the atomization chamber 120.

[0068] Specifically, the float valve 200 is configured as a deformable structure. The float valve 200 can be, but is not limited to, a silicone structure, a rubber structure, a plastic structure, etc.

[0069] When the liquid level in the atomization chamber 120 is higher than or equal to the first preset liquid level, at this time, the buoyancy of the liquid in the atomization chamber 120 acting on the float valve 200 in the atomization chamber 120 is greater than the gravity of the float valve 200 itself. The float valve floats up to a position where it completely blocks the liquid passage 130. At the same time, the liquid in the atomization chamber 120 exerts a buoyancy force on the float valve 200 towards the liquid passage 130, causing the float valve 200 to press tightly against the end port of the liquid passage 130 communicating with the atomization chamber 120. Then, by utilizing the deformable material property of the float valve 200, in this way, when the liquid level in the atomization chamber 120 is higher than or equal to the first preset liquid level, the float valve 200 forms an interference fit with the port of the liquid passage 130, eliminating the gap between the float valve 200 and the port of the liquid passage 130, and enabling the float valve 200 to completely block the liquid passage 130.

[0070] In some embodiments of the present application, refer to Figure 4 、 Figure 5 and Figure 6 , where in Figure 4 、 Figure 5 and Figure 6 , the float valve 200 is in a state of blocking the liquid passage 130.

[0071] The float valve 200 includes a gravity part 210 and a blocking part 220 connected to the top of the gravity part 210. The blocking part 220 vertically penetrates the liquid passage 130, and a stop surface 230 for blocking or opening the liquid passage 130 is formed at the connection between the blocking part 220 and the gravity part 210.

[0072] Specifically, the two ends of the liquid passage 130 are respectively an inlet end and an outlet end. The inlet end of the liquid passage 130 communicates with the liquid storage chamber 110, and the inlet end of the liquid passage 130 is always lower than the liquid level in the liquid storage chamber 110, ensuring that when the liquid passage 130 is opened, the liquid storage chamber 110 can input liquid into the atomization chamber 120 through the liquid passage 130, so that the liquid in the atomization chamber 120 can be normally supplied. The outlet end of the liquid passage 130 communicates with the atomization chamber 120.

[0073] When the liquid level in the atomization chamber 120 is higher than or equal to the first preset liquid level, at this time, the buoyancy of the liquid in the atomization chamber 120 acting on the float valve 200 in the atomization chamber 120 is greater than the gravity of the float valve 200 itself. The entire float valve 200 rises under the action of the buoyancy, so that the blocking portion 220 at the top of the float valve 200 passes through the outlet end of the liquid passing channel 130 and is vertically arranged in the liquid passing channel 130 until the stop surface 230 formed between the blocking portion 220 and the gravity portion 210 abuts and cooperates with the outlet end of the liquid passing channel 130. At this time, the stop surface 230 formed between the blocking portion 220 and the gravity portion 210 blocks the outlet end of the liquid passing channel 130, realizing the complete blocking of the liquid passing channel 130.

[0074] It can be understood that by forming the stop surface 230 between the gravity portion 210 and the blocking portion 220 of the float valve 200, when the float valve 200 floats or sinks based on the liquid level in the atomization chamber 120, the stop surface 230 on the float valve 200 can correspondingly block or open the port of the liquid passing channel 130. Without setting an additional transmission structure or driving structure, the communication between the atomization chamber 120 and the liquid storage chamber 110 can be dynamically conducted or blocked, so that the liquid level in the atomization chamber 120 is always maintained within a preset liquid level range, ensuring the normal replenishment of the liquid in the atomization chamber 120, avoiding the atomization function failure caused by the lack of liquid in the atomization chamber 120, and enabling the stable operation of the atomization device.

[0075] Further, referring to Figure 4 、 Figure 5 and Figure 6 ,the liquid passing channel 130 includes a connected horizontal section 131 and a vertical section 132. The horizontal section 131 is communicated with the liquid storage chamber 110, and the vertical section 132 is communicated with the atomization chamber 120. The blocking portion 220 is vertically arranged in the vertical section 132 and forms a first liquid passing gap 133 with the vertical section 132. The vertical projection of the vertical section 132 relative to the stop surface 230 is within the stop surface 230.

[0076] Specifically, the liquid passing channel 130 is constructed as an L-shaped circular pipe, and the liquid passing channel 130 is integrally formed inside the box body 100. The inner diameters of the horizontal section 131 and the vertical section 132 of the liquid passing channel 130 are equal or may not be equal.

[0077] Correspondingly, the gravity portion 210 of the float valve 200 is constructed as a spherical structure, and the blocking portion 220 of the float valve 200 is constructed as a rod-shaped structure, which not only forms the stop surface 230 between the gravity portion 210 and the blocking portion 220, but also facilitates the vertical arrangement of the blocking portion 220 in the vertical section 132 of the liquid passing channel 130.

[0078] Further, the blocking part 220 is configured as a round rod shape, and the outer diameter of the blocking part 220 is smaller than the inner diameter of the vertical section 132 of the liquid passing channel 130, so that when the blocking part 220 vertically penetrates into the vertical section 132, a first liquid passing gap 133 can be formed between the blocking part 220 and the vertical section 132. At the same time, the vertical projection of the vertical section 132 relative to the stop surface 230 is within the stop surface 230, avoiding structural interference between the blocking part 220 and the vertical section 132 when the blocking part 220 penetrates into the vertical section 132.

[0079] In addition, the gravity part 210 and the blocking part 220 of the float valve 200 are respectively configured as a spherical structure and a rod-shaped structure. When the rod-shaped blocking part 220 is inserted into the liquid passing channel 130 and is in a position state where the liquid passing channel 130 is not completely blocked, when the liquid in the liquid passing channel 130 flows into the atomization chamber 120, the liquid will flow along the rod wall instead of directly flushing out from the liquid passing channel 130, reducing the noise generated when the liquid in the liquid passing channel 130 flows into the atomization chamber 120 to a certain extent.

[0080] It is not difficult to understand that when the liquid level in the atomization chamber 120 is higher than or equal to the first preset liquid level, at this time, the blocking part 220 on the float valve 200 vertically penetrates into the vertical section 132, and at the same time, the stop surface 230 formed between the blocking part 220 and the gravity part 210 blocks the port of the vertical section 132, and also blocks the port of the first liquid passing gap 133. At this time, the liquid in the liquid storage chamber 110 cannot be supplied to the atomization chamber 120.

[0081] As the liquid in the atomization chamber 120 is atomized and consumed by the atomization component 300, the liquid level in the atomization chamber 120 decreases, and the buoyancy force received by the entire float valve 200 also decreases. The float valve 200 gradually moves downward, that is, the gravity part 210 of the float valve 200 drives the vertical section 132 thereon to move downward. The stop surface 230 formed between the blocking part 220 and the gravity part 210 opens the port of the vertical section 132, and the blocking part 220 also gradually moves downward and disengages from the vertical section 132. During this process, the liquid in the vertical section 132 flows into the atomization chamber 120 through the first liquid passing gap 133 and the port of the vertical section 132, so that the liquid level in the atomization chamber 120 is always maintained within a preset liquid level range.

[0082] Further, in the float valve 200 of the embodiment of the present application, see Figure 6 , the gravity part 210 and the blocking part 220 are configured as an integrally formed structure.

[0083] Specifically, the mass of the gravity part 210 is greater than the mass of the blocking part 220, and the gravity part 210 and the blocking part 220 are made of the same material, such as silicone material, to avoid the overall weight of the float valve 200 being too heavy to float under the buoyancy force of the liquid in the atomization chamber 120.

[0084] By integrally forming the gravity part 210 and the blocking part 220 into the float valve 200, the overall forming process of the float valve 200 can be reduced, the forming efficiency of the float valve 200 can be improved, which is beneficial to the large-scale production of the atomization device.

[0085] Further, referring to Figure 6 , a flared portion 134 is formed at the bottom end of the liquid passing channel 130.

[0086] Specifically, the flared portion 134 is formed at the bottom end of the vertical section 132 of the liquid passing channel 130, and the diameter of the flared portion 134 is larger than the inner diameter of the liquid passing channel 130.

[0087] By forming the flared portion 134 at the bottom end of the liquid passing channel 130, the flared portion 134 can provide positioning and guidance for the vertical penetration or detachment of the blocking part 220 of the float valve 200 from the liquid passing channel 130, and also reduces the risk of structural interference between the blocking part 220 of the float valve 200 and the liquid passing channel 130.

[0088] In some embodiments of the present application, referring again to Figure 2 , Figure 3 or Figure 4 and Figure 5 , a float chamber 140 communicating with the atomization chamber 120 is formed at the bottom of the atomization chamber 120. The liquid storage chamber 110 is communicated with the float chamber 140 through the liquid passing channel 130. The float valve 200 is disposed in the float chamber 140 in a liftable manner, and the float chamber 140 can limit the float valve 200 along the length direction X and the width direction Y of the float valve 200.

[0089] Specifically, the outer wall or the upper end of the float chamber 140 is open, so that the float chamber 140 is open to communicate with the atomization chamber 120, ensuring that the liquid in the float chamber 140 can freely flow into the atomization chamber 120.

[0090] By forming the float chamber 140 communicating with the atomization chamber 120 at the bottom of the atomization chamber 120 and limiting the float valve 200 along the length direction X and the width direction Y of the float valve 200 by the float chamber 140, the float valve 200 only has the freedom of movement to lift and lower in the atomization chamber 120, avoiding the problem that the float valve 200 is offset to both sides due to the buoyancy of the liquid in the atomization chamber 120 or the float chamber 140 or the liquid impact force at the port of the liquid passing channel 130, resulting in difficulty in aligning with the liquid passing channel 130 and blocking the liquid passing channel 130, and ensuring the stability of the float valve 200 to block or open the liquid passing channel 130 through the lifting action.

[0091] Further, referring to Figure 2 , Figure 3 or Figure 7 , Figure 8, a plurality of retaining ribs 150 are provided at the bottom of the box body 100, and all the retaining ribs 150 and the inner wall of the box body 100 surround to form a float chamber 140, and a second liquid passing gap 160 communicating with the atomization chamber 120 is formed between two adjacent retaining ribs 150.

[0092] Specifically, the plurality of retaining ribs 150 and the box body 100 are of an integrally formed structure, which simplifies the forming process of the float chamber 140.

[0093] It can be understood that all the retaining ribs 150 are located at the outer walls in the length direction X and the width direction Y of the float valve 200. In this way, the function of limiting the float valve 200 in the length direction X and the width direction Y of the float valve 200 is realized, so that the float valve 200 can only perform a single lifting movement in the height direction Z, ensuring the stability of the float valve 200 to block or open the liquid passing channel 130 through the lifting action.

[0094] The second liquid passing gap 160 formed between two adjacent retaining ribs 150 ensures that there is a sufficiently large communication gap between the float chamber 140 and the atomization chamber 120, ensuring that the liquid in the liquid storage chamber 110 can freely flow into the atomization chamber 120 in the conducting state of the liquid passing channel 130, so that the liquid in the atomization chamber 120 can be normally supplied.

[0095] It should also be noted that, based on the embodiment in which the gravity part 210 and the blocking part 220 of the float valve 200 are respectively constructed as a spherical structure and a rod-shaped structure, when the stop surface 230 formed by the gravity part 210 and the blocking part 220 blocks the port of the liquid passing channel 130, the rod-shaped blocking part 220 is inserted into the liquid passing channel 130, and the outer wall of the spherical gravity part 210 is in stop limit cooperation with the retaining rib 150, ensuring that the float valve 200 is in force balance as a whole when blocking the liquid passing channel 130, so that the float valve 200 will not be flipped due to liquid impact, ensuring that the float valve 200 stably blocks the liquid passing channel 130.

[0096] Of course, in other embodiments, a plurality of baffles may also be provided at the bottom of the box body 100, and all the baffles and the bottom wall of the box body 100 surround to form a float chamber 140, and a second liquid passing gap 160 communicating with the atomization chamber 120 is formed between two adjacent baffles, that is, two adjacent baffles are spaced apart to form a second liquid passing gap 160 for the liquid to freely flow, so that the liquid in the atomization chamber 120 can be normally supplied.

[0097] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0098] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
