[0002] At present, air handling equipment with a water tank, such as a humidifier, needs to be equipped with a water level detection structure to detect the water level in the water tank. For example, some models of humidifiers use a float bottle that rises and falls with the water level in the water tank to detect whether the water level in the water tank is sufficient.

[0003] During the use of the float bottle, the internal and external air pressure needs to be kept consistent to avoid depressions or bulges on the surface of the float bottle. Usually, an air vent is directly opened on the surface of the float bottle. This structure usually causes water to enter the float bottle when adding water to the water tank, increasing the design weight of the float bottle and affecting the buoyancy of the float bottle, which in turn leads to inaccurate water level detection. Utility Model Content

[0006] The float bottle assembly of the utility model arranges the air pressure balance assembly in the air flow channel of the outer wall of the float bottle body. When the air pressure inside and outside the float bottle body is the same, the sealing matching part cooperates with the sealing convex part to cut off the air flow channel; when the air pressure inside and outside the float bottle body is different, the sealing matching part and the sealing convex part of the air pressure balance assembly are separated from each other to conduct the air flow channel, so that the air pressure inside and outside the float bottle body is restored to balance, and the float bottle body is prevented from bulging or sinking due to the different air pressure inside and outside. Moreover, compared with the solution in the related art that directly opens air holes on the float bottle to balance the air pressure, which causes water to enter the float bottle from the air holes, the air pressure balance assembly of the present application can prevent water in the water tank from entering the float bottle body through the air flow channel and affecting the buoyancy of the float bottle body. In this way, the working reliability of the float bottle assembly can be guaranteed and the accuracy of the water level detection result can be improved.

[0007] In some embodiments, the air pressure balance component is configured to be movable relative to the sealing protrusion as the air pressure between the cavity and the outside changes, so as to drive the sealing mating portion to move axially along the air flow channel relative to the sealing protrusion.

[0008] Through the sealing cooperation between the sealing cooperation part and the sealing convex part of the air pressure balance component, when the external air pressure is greater than the air pressure in the cavity, the external air pressure pushes the air pressure balance component to drive the sealing cooperation part to move into the cavity, the sealing cooperation part and the sealing convex part are staggered, the air flow channel is connected, the external air pressure and the air pressure in the cavity are gradually equal, the sealing cooperation part and the sealing convex part are reset to the position of cutting off the air flow channel, when the external air pressure is less than the air pressure in the cavity, the air pressure in the cavity pushes the air pressure balance component to drive the sealing cooperation part to move away from the cavity, the sealing cooperation part and the sealing convex part are staggered, the air flow channel is connected, the external air pressure and the air pressure in the cavity are gradually equal, the sealing cooperation part and the sealing convex part are reset to the position of cutting off the air flow channel, automatically balancing the cavity of the floating bottle body and the external air pressure, which is convenient and quick.

[0014] The connecting column and the connecting hole are connected by threads, and the structure is simple and the processing is convenient. During production and assembly, workers only need to tighten the connecting column into the connecting hole to connect the first valve stem and the second valve stem, making the assembly of the first valve stem and the second valve stem simple and convenient.

[0015] According to some embodiments of the present invention, the invention further comprises: an elastic member, wherein the elastic member is fixedly disposed on the sealing protrusion, and the elastic member is respectively abutted and matched with the first head and the second head.

[0016] After the sealing mating part of the air pressure balancing assembly moves relative to the sealing protrusion to open the air flow channel, the elastic member applies force to the first head and the second head respectively to reset the sealing mating part. The provision of the elastic member is helpful to improve the reliability of the sealing mating part resetting process.

[0020] In the process of the air pressure balance assembly balancing the cavity of the float bottle body and the external air pressure, under the action of the gas on the side with high air pressure, the air pressure balance assembly drives the sealing mating part to move toward the side with low air pressure, and the end of the first elastic member facing the sealing protrusion is respectively embedded in the first fixing groove and the end of the second elastic member facing the sealing protrusion is embedded in the second fixing groove for fixation, so as to avoid the elastic member on the side with low air pressure from being disconnected from the sealing protrusion during movement, thereby ensuring the effectiveness of the force exerted by the elastic member on the air pressure balance assembly and improving the reliability of the structure.

[0053] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0054] At present, air handling equipment with a water tank, such as a humidifier, needs to be equipped with a water level detection structure to detect the water level in the water tank. For example, some models of humidifiers use a float bottle that rises and falls with the water level in the water tank to detect whether the water level in the water tank is sufficient.

[0055] During the use of the float bottle, the internal and external air pressure needs to be kept consistent to avoid the appearance or bulging of the float bottle surface. Usually, an air vent is directly opened on the surface of the float bottle. This structure usually causes water to enter the float bottle when adding water to the water tank, increasing the design weight of the float bottle and affecting the buoyancy of the float bottle, which in turn leads to inaccurate water level detection.

[0056] In view of this, the utility model provides a float bottle assembly, a water tank and an air treatment device. Through the sealing cooperation between the sealing cooperation part and the sealing convex part of the air pressure balance assembly, the internal and external air pressure difference of the float bottle body is consistent, and the detection result of the water level in the water tank is accurate.

[0057] Reference below Figure 1-Figure 9 A float bottle assembly according to a first aspect of the utility model is described.

[0058] refer to Figure 1-Figure 5 A floating bottle assembly 100 can be used to detect the water level of a water tank 200. The floating bottle assembly 100 can include a floating bottle body 110 and an air pressure balance assembly 130.

[0059] The inner side of the float bottle body 110 has a cavity 111 to ensure the buoyancy of the float bottle body 110. The outer wall of the float bottle body 110 is provided with an airflow channel 121, which connects the cavity and the outside, and the channel wall of the airflow channel 121 is provided with a sealing protrusion 122 protruding radially inward, wherein the airflow channel 121 can be formed by the outer wall of the float bottle body 110 itself, or a channel structure (such as the fixing sleeve described below) can be provided on the outer wall of the float bottle body 110 to form the airflow channel 121.

[0060] The principle of the floating bottle body 110 detecting the water level is as follows: in the air treatment device 300, the upper part of the box body 210 of the water tank 200 is provided with a water level alarm matched with the top of the floating bottle body 110. During normal use, the amount of water in the box body 210 is sufficient. Under the action of buoyancy, the top of the floating bottle body 110 presses against the water level alarm, and the water level alarm does not alarm. With the use of the air treatment device 300, the water level in the water tank 200 gradually decreases, the floating bottle body 110 gradually decreases, the floating bottle body 110 is disconnected from the water level alarm, and the water level alarm alarms. At this time, the water level in the water tank 200 is too low, reminding the user to add water.

[0061] The air pressure balance component 130 is arranged in the air flow channel 121, and the air pressure balance component 130 is provided with a sealing matching part 131 that matches the shape of the sealing protrusion 122. The matching between the sealing protrusion 122 and the sealing matching part 131 can be: when the air pressure of the cavity 111 is equal to that of the outside, the sealing matching part 131 cooperates with the sealing protrusion 122 to cut off the air flow channel 121, so that the cavity 111 of the floating bottle has good air tightness; when the air pressure of the cavity 111 is not equal to that of the outside, the sealing matching part 131 separates from the sealing protrusion 122 to make the air flow channel 121 conductive, so that the air pressure of the cavity 111 and the outside gradually restores the balance.

[0062] For example, the sealing mating part 131 is separated from the sealing protrusion 122. The sealing protrusion 122 may be stationary, and the air pressure balancing component 130 moves relative to the sealing protrusion 122 to stagger the sealing mating part 131 and the sealing protrusion 122. Alternatively, the air pressure balancing component 130 is stationary as a whole, and the sealing protrusion 122 moves relative to the air pressure balancing component 130 to stagger the sealing mating part 131 and the sealing protrusion 122 to balance the air pressure in the cavity 111 and the outside world.

[0063] In addition, at least one of the sealing matching part 131 and the sealing protrusion 122 may be deformed under the action of air pressure, so that the two are out of coordination and the airflow channel 121 is opened. For example, at least one of the sealing matching part 131 and the sealing protrusion 122 may be elastic, for example, the sealing matching part 131 may be elastic, or the sealing protrusion 122 may be elastic, or both the sealing matching part 131 and the sealing protrusion 122 may be elastic. The elasticity of the sealing matching part 131 and the sealing protrusion 122 may come from their respective materials, and the elastic material here may be selected from silicone, rubber or elastic plastic, etc. In this way, the sealing matching part 131 and the sealing protrusion 122 can block or open the airflow channel 121 by deformation.

[0064] The sealing protrusion 122 cooperates with the sealing matching part 131. The sealing protrusion 122 may be annular, and the sealing matching part 131 may be circular. The sealing protrusion 122 and the sealing matching part 131 are pressed and abutted to close the airflow channel 121, or the sealing protrusion 122 and the sealing matching part 131 are staggered to open the airflow channel 121. Of course, the cooperation between the sealing protrusion 122 and the sealing matching part 131 may also be in other forms. For example, the sealing protrusion 122 may also be a multi-section polygonal structure distributed circumferentially, and the sealing matching part 131 may be a multi-section polygonal structure matching the sealing protrusion 122. They are connected in a manner similar to the engagement of an internal gear and an external gear, and the effect of closing the airflow channel 121 or opening the airflow channel 121 can also be achieved.

[0065] In the floating bottle assembly 100 of the utility model, the air pressure balance assembly 130 is arranged in the air flow channel 121 of the outer wall of the floating bottle body 110. When the air pressure inside and outside the floating bottle body 110 is the same, the sealing matching portion 131 cooperates with the sealing convex portion 122 to cut off the air flow channel 121; when the air pressure inside and outside the floating bottle body 110 is different, the sealing matching portion 131 and the sealing convex portion 122 of the air pressure balance assembly 130 are separated from each other, and the air flow channel 121 is opened, so that the air pressure inside and outside the floating bottle body 110 is equal. The pressure is restored to balance, thereby preventing the float bottle body 110 from bulging or sinking due to the difference in internal and external air pressure. Moreover, compared with the solution in the related art of directly opening air holes on the float bottle to balance the air pressure, which allows water to enter the float bottle through the air holes, the air pressure balance assembly 130 of the present application can prevent the water in the water tank from entering the float bottle body through the air flow channel 121 and affecting the buoyancy of the float bottle body 110. In this way, the working reliability of the float bottle assembly 100 can be guaranteed and the accuracy of the water level detection results can be improved.

[0066] In some embodiments, the outer wall of the float bottle body 110 is provided with an installation space and a vent hole 112, which communicates with the installation space and the cavity 111. A fixing sleeve 120 may be fixedly arranged in the installation space, and the fixing sleeve 120 defines an air flow channel 121, which communicates with the vent hole 112.

[0067] By setting the installation space, the fixing sleeve 120 has a structural foundation to be set on the floating bottle body 110, and the sealing protrusion 122 is set in the air flow channel 121 of the fixing sleeve 120. The fixing sleeve 120 with the sealing protrusion 122 and the floating bottle body 110 are designed as a split structure. The fixing sleeve 120 and the floating bottle body 110 can be produced separately first, and then the fixing sleeve 120 is assembled to the installation space. In this way, after the sealing effect of the sealing protrusion 122 is reduced or even fails, the user only needs to replace the fixing sleeve 120, which is conducive to improving user satisfaction.

[0068] refer to Figures 3 to 8 In some embodiments, one of the side wall of the installation space and the peripheral wall of the fixing sleeve 120 is provided with a fixing protrusion 113, and the other is provided with a fixing groove 123 adapted to the fixing protrusion 113. For example, the side wall of the installation space may be provided with the fixing protrusion 113, and the fixing sleeve 120 may be provided with the fixing groove 123, or the peripheral wall of the fixing sleeve 120 may be provided with the fixing protrusion 113, and the side wall of the installation space may be provided with the fixing groove 123. The fixing sleeve 120 is fixed by embedding the fixing protrusion 113 in the fixing groove 123, thereby blocking the air vent 112 of the float bottle body 110, improving the sealing effect of the interior of the cavity 111 of the float bottle body 110, and preventing water from entering the float bottle body 110.

[0069] refer to Figures 3 to 5Furthermore, the fixing sleeve 120 is elastic, that is, the fixing sleeve 120 is an elastic member, so that the fixing sleeve 120 has a certain deformation margin, which facilitates the fixing protrusion 113 to be embedded in the fixing groove 123, so that the fixing sleeve 120 is easy to install in the installation space, and damage to the fixing sleeve 120 is avoided. In addition, it is also helpful to improve the sealing of the airflow channel 121 in the partition state. Optionally, the fixing sleeve 120 can be a rubber sleeve or a silicone sleeve, which is easy to manufacture and has a low cost.

[0070] Continue to refer Figures 3 to 5 In some embodiments, the air pressure balance assembly 130 is configured to be movable relative to the fixed sleeve 120 as the air pressure between the cavity 111 and the outside changes, so as to drive the sealing mating portion 131 to move axially along the air flow channel 121 relative to the sealing protrusion 122 .

[0071] The movement of the air pressure balance component 130 may include: when the external air pressure is greater than the air pressure in the cavity 111, the external air pressure pushes the air pressure balance component 130 to drive the sealing mating part 131 to move into the cavity 111, the sealing mating part 131 and the sealing protrusion 122 are staggered, the air flow channel 121 is connected, the external air pressure and the air pressure in the cavity 111 are gradually equal, and the sealing mating part 131 and the sealing protrusion 122 are reset to the position of cutting off the air flow channel 121; when the external air pressure is less than the air pressure in the cavity 111, the air pressure in the cavity 111 pushes the air pressure balance component 130 to drive the sealing mating part 131 to move away from the cavity 111, the sealing mating part 131 and the sealing protrusion 122 are staggered, the air flow channel 121 is connected, the external air pressure and the air pressure in the cavity 111 are gradually equal, and the sealing mating part 131 and the sealing protrusion 122 are reset to the position of cutting off the air flow channel 121. In this way, the air pressure in the cavity 111 of the floating bottle body 110 and the outside air pressure can be automatically balanced by the air pressure balance assembly 130. The working principle is simple and easy to implement.

[0072] refer to Figures 6 to 9 According to some embodiments of the present invention, the air pressure balance assembly 130 may include: a first valve stem 132 and a second valve stem 133, wherein the first valve stem 132 includes a first stem portion 1321 and a first head portion 1322, the size of the first head portion 1322 is larger than the size of the first stem portion 1321, and the second valve stem 133 includes a second stem portion 1331 and a second head portion 1332, the size of the second head portion 1332 is larger than the size of the second stem portion 1331.

[0073] The first head portion 1322 and the second head portion 1332 are respectively located on both sides of the sealing protrusion 122 along the axial direction of the airflow channel 121, the first rod portion 1321 and the second rod portion 1331 are connected and are commonly provided on the sealing protrusion 122, and the sealing matching portion 131 is formed on at least one of the first rod portion 1321 and the second rod portion 1331. For example, the sealing matching portion 131 can be formed on the first rod portion 1321, or the sealing matching portion 131 can be formed on the second rod portion 1331, or the first rod portion 1321 and the second rod portion 1331 each have a partial structure of the sealing matching portion 131, and when the first rod portion 1321 and the second rod portion 1331 are connected, they are combined to form the sealing matching portion 131.

[0074] It can be understood that in order to prevent the air pressure balance component 130 from escaping from the air flow channel 121, the two ends of the air pressure balance component 130 can be limited by the sealing protrusion 122. For example, the radial dimensions of the first head 1322 and the second head 1332 both exceed the inner diameter of the sealing protrusion 122, so that the first head 1322 and the second head 1332 can be respectively abutted and limited with the two sides of the sealing protrusion 122.

[0075] In this embodiment, the air pressure balance component 130 is configured to be a split first valve stem 132 and a second valve stem 133. The first valve stem 132 and the second valve stem 133 are connected by the first rod portion 1321 and the second rod portion 1331. When the air pressure balance component 130 is installed in the air flow channel 121, the first rod portion 1321 and the second rod portion 1331 form a whole that is penetrated on the inner side of the sealing protrusion 122, so that the air pressure balance component 130 can drive the sealing mating portion 131 to move. The overall working principle and structure are relatively simple and easy to assemble.

[0076] refer to Figure 7 , Figure 8 and Fig. 9 Furthermore, a connecting hole 13211 extending axially along the airflow channel 121 is provided at one end of the first rod portion 1321 toward the second rod portion 1331, and a connecting column 13311 is provided at one end of the second rod portion 1331 toward the first rod portion 1321, and the connecting column 13311 is passed through the connecting hole 13211.

[0077] The first valve stem 132 and the second valve stem 133 are fixed by the connecting column 13311 passing through the connecting hole 13211, which is convenient for installation. The connection between the connecting column 13311 and the connecting hole 13211 can be achieved by plugging, clamping, bonding or screwing.

[0078] Continue to refer Figure 7 , Figure 8 and Fig. 9Furthermore, a connecting thread is provided on the hole wall of the connecting hole 13211, a matching thread is provided on the outer wall of the connecting column 13311, and the connecting column 13311 and the second rod portion 1331 are threadedly matched.

[0079] The connecting column 13311 and the connecting hole 13211 are connected by threads, which has a simple structure and is easy to process. During production and assembly, the first valve stem 132 and the second valve stem 133 can be connected by simply tightening the connecting column 13311 into the connecting hole 13211, making the assembly process of the first valve stem 132 and the second valve stem 133 convenient.

[0080] refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 According to some embodiments of the present invention, the float bottle assembly 100 may further include an elastic member 140 , which is fixedly disposed on the sealing protrusion 122 , and the elastic member 140 is respectively abutted against the first head 1322 and the second head 1332 .

[0081] Here, the elastic member 140 may be arranged in such a manner that: the elastic member 140 is arranged as one, sleeved on the first rod portion 1321 and the second rod portion 1331, and the two ends thereof are respectively in contact with the first head portion 1322 and the second head portion 1332, a mounting gap is provided in the middle of the elastic member 140, the sealing protrusion 122 is clamped in the mounting gap, and the two ends of the elastic member 140 respectively apply elastic forces to the first valve stem 132 and the second valve stem 133;

[0082] Alternatively, in other embodiments, the elastic member 140 may be arranged in such a manner that two elastic members 140 are arranged, respectively located on both sides of the sealing protrusion 122, wherein the two ends of one elastic member 140 respectively abut against the first head 1322 and the side of the sealing protrusion 122 facing the first head 1322, and the two ends of the other elastic member 140 respectively abut against the second head 1332 and the side of the sealing protrusion 122 facing the second head 1332, so that the two elastic members 140 can respectively apply elastic force to the first valve stem 132 and the second valve stem 133.

[0083] After the sealing fitting part 131 of the air pressure balancing assembly 130 moves relative to the sealing protrusion 122 to open the airflow channel 121, the two elastic members 140 respectively apply forces to the first head 1322 and the second head 1332 to reset the sealing fitting part 131. The provision of the elastic member 140 is helpful to improve the reliability of the resetting process of the sealing fitting part 131.

[0084] Optionally, the elastic member 140 may be an elastic sleeve with elasticity, or a compression spring. In this way, the structure of the elastic member 140 is relatively simple and the cost can be reduced.

[0085] refer to Figure 8 and Fig. 9 Furthermore, the first abutting surface 1221 is provided with a first fixing groove 12211, and one end of the first elastic member 141 facing the sealing protrusion 122 is embedded in the first fixing groove 12211; the second abutting surface 1222 is provided with a second fixing groove 12221, and one end of the second elastic member 142 facing the sealing protrusion 122 is embedded in the second fixing groove 12221. During the process of the air pressure balance component 130 balancing the cavity 111 of the float bottle body 110 and the external air pressure, under the action of the gas on the side with high air pressure, the air pressure balance component 130 drives the sealing mating part 131 to move toward the side with low air pressure, and respectively embeds one end of the first elastic member 141 toward the sealing protrusion 122 in the first fixing groove 12211 and one end of the second elastic member 142 toward the sealing protrusion 122 in the second fixing groove 12221 for fixation, so as to avoid the elastic member 140 on the side with low air pressure from being disconnected from the sealing protrusion 122 during movement, thereby ensuring the effectiveness of the force applied by the elastic member 140 to the air pressure balance component 130 and improving the reliability of the structure.

[0086] The working principle of the floating bottle assembly 100 of the utility model is:

[0087] like Figure 3 As shown, when the air pressure in the cavity 111 is consistent with the external air pressure, the sealing protrusion 122 and the sealing matching portion 131 are pressed and contacted to close the air flow channel 121; Figure 4 As shown, when the external air pressure is greater than the air pressure in the cavity 111, the external air pressure pushes the air pressure balance assembly 130 to drive the sealing mating part 131 to move into the cavity 111, the sealing mating part 131 and the sealing protrusion 122 are staggered, the air flow channel 121 is connected, the external air pressure and the air pressure in the cavity 111 gradually become equal, and the sealing mating part 131 and the sealing protrusion 122 are reset to the position of cutting off the air flow channel 121.

[0088] like Figure 5 As shown, when the external air pressure is lower than the air pressure in the cavity 111, the air pressure in the cavity 111 pushes the air pressure balancing assembly 130 to drive the sealing mating portion 131 to move away from the cavity 111, the sealing mating portion 131 and the sealing protrusion 122 are staggered, the air flow channel 121 is connected, the external air pressure and the air pressure in the cavity 111 are gradually equalized, the sealing mating portion 131 and the sealing protrusion 122 are reset to the position of cutting off the air flow channel 121, and the cavity 111 of the float bottle body 110 and the external air pressure are automatically balanced.

[0090] The box body 210 defines a water storage cavity, the float bottle bracket 220 is disposed in the water storage cavity, the float bottle bracket 220 defines a floating space communicated with the water storage cavity, and the float bottle assembly 100 can be floatably disposed in the floating space.

[0091] During the use of the air treatment equipment 300, the water level in the water tank 200 gradually decreases, the position of the float bottle assembly 100 gradually decreases, and it is disconnected from the water level alarm above the water tank 200. The water level alarm then sends a low water level alarm to remind the user to add water.

[0092] Of course, the water tank 200 may further include a filter element, which is disposed on the peripheral side of the float bottle support 220 to filter the water in the water tank 200 .

[0093] The water tank 200 of the present invention uses the above-mentioned float bottle assembly 100. Under the action of the air pressure balance assembly 130, the float bottle assembly 100 automatically balances the cavity 111 of the float bottle body 110 and the external air pressure. The cavity 111 has good airtightness and will not get water in, so the water level detection effect is accurate.

[0094] refer to Fig.10 The third aspect of the utility model further provides an air treatment device 300, which may include the above-mentioned water tank 200 and a water level alarm cooperating with the float bottle body 110. When the water level in the water tank 200 is insufficient, the water level alarm sounds an alarm to remind the user to add water.

[0095] Of course, the air treatment device 300 may also include an air duct housing and a humidification component, the water tank 200 supplies water to the humidification component, and the air duct housing sends out humid air.

[0096] The air treatment device 300 of the utility model uses the water tank 200, so the water level in the water tank 200 is accurately detected, and the user is reminded of the correct timing for adding water.
