Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and more specifically to a humidifier with a two-way piston valve. Background Technology

[0002] A humidifier is a device that uses an ultrasonic atomizer to convert water into water mist, which is then sprayed into the air to increase humidity.

[0003] Most humidifiers on the market currently use a separate design for the water tank and base. Their water supply mainly relies on a "one-way valve + float" structure to control the water supply from the tank to the base. When the water level in the base drops, the float falls, opening the one-way valve and allowing water to flow into the base; when the water level rises, the float rises and closes the one-way valve.

[0004] However, traditional floating structure has the following problems:

[0005] 1. It occupies internal space of the water tank or base, which is not conducive to miniaturization design;

[0006] 2. The float itself is a moving part and has a limited service life;

[0007] 3. The complex structure increases the difficulty of manufacturing and assembly.

[0008] In order to overcome the problems existing in the prior art, the applicant proposes the following humidifier with a two-way piston valve. Utility Model Content

[0009] In view of this, the present invention provides a humidifier with a bidirectional piston valve.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: a humidifier with a two-way piston valve, comprising: a base and an upper body;

[0011] The base is equipped with an ultrasonic atomization chamber.

[0012] The upper fuselage is equipped with a water storage chamber;

[0013] The ultrasonic atomizing chamber and the water storage chamber are connected by a fluid channel; a two-way piston valve is provided corresponding to the fluid channel.

[0014] The bidirectional piston valve includes: a valve stem, an upper valve plate, a lower valve plate, a spring, and a float;

[0015] The upper and lower valve plates are mounted on the valve stem and face away from each other; the spring is sleeved on the valve stem and located between the upper and lower valve plates; the float is located at the end of the valve stem; after the upper body is assembled on the base, the float is located in the ultrasonic atomization chamber.

[0016] In a preferred embodiment of this utility model, both the upper valve plate and the lower valve plate are arranged in an umbrella shape; the upper valve plate is located inside the water storage cavity; and the lower valve plate is located inside the ultrasonic atomization cavity.

[0017] As a preferred embodiment of this utility model, a circular ring plate is provided in the fluid channel, and the periphery of the circular ring plate is partially connected to the inner wall of the fluid channel.

[0018] The valve stem passes through the center of the annular plate;

[0019] One end of the spring is supported on the bottom surface of the annular plate, and the other end is supported on the lower valve plate.

[0020] In a preferred embodiment of this utility model, after the upper body is assembled onto the base, the float abuts against the inner bottom wall of the ultrasonic atomizing cavity.

[0021] As a preferred embodiment of this utility model, the ultrasonic atomizing cavity is provided with a top column below the float.

[0022] As a preferred embodiment of this utility model, the upper body includes: a bottom shell with an atomization channel and an upper shell; the atomization channel is connected to the ultrasonic atomization cavity.

[0023] As a preferred embodiment of this utility model, the top of the upper shell is provided with a cover, and the cover is provided with a mist outlet.

[0024] As a preferred embodiment of this utility model, the ultrasonic atomizing cavity is provided with an ultrasonic atomizer.

[0025] In a preferred embodiment of this utility model, the base has an installation cavity below the ultrasonic atomizing cavity; a PCB board is installed inside the installation cavity; and the ultrasonic atomizer is electrically connected to the PCB board.

[0026] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:

[0027] 1. The bidirectional piston valve in this application has a valve stem with an upper valve plate and a lower valve plate. The valve stem moves up and down, causing the upper and lower valve plates to move, thereby closing the fluid channel. After the upper body is removed from the base, the upper valve plate closes the upper end of the fluid channel to prevent water in the water storage chamber from flowing out, thus facilitating water filling.

[0028] After the upper body is installed on the base, the valve rod is pushed upward by the top column, opening the fluid channel and allowing water in the water storage chamber to flow into the ultrasonic atomization chamber. When the water level in the ultrasonic atomization chamber reaches the specified level, the float rises with the change in water level, causing the lower valve plate to close the lower end of the fluid channel. The float moves the valve rod up and down with the rise and fall of the water level.

[0029] 2. This utility model uses a two-way piston valve, while eliminating the float and one-way valve in the traditional structure, simplifying the structure and achieving a reliable and space-saving water supply control method; the product has a compact structure, which is conducive to flexible water tank design and can be adapted to various shapes;

[0030] 3. This utility model has high reliability, the piston-type mechanical seal is more durable, the response is sensitive, and the water level change control is timely and accurate.

[0031] The remaining beneficial technical effects of this utility model are embodied in the specific embodiments. Attached Figure Description

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0046] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] For humidifiers with a two-way piston valve, please refer to [link / reference]. Figure 1-9 As shown, it includes: a base 100 and an upper body 200. The base 100 and the upper body 200 are separate structures, that is, the upper body 200 can be placed on the base 100 or removed from the base 100.

[0048] More specifically, the upper body 200 can be placed directly on the base 100; and in order to make the upper body 200 more stably installed on the base 100, the two can be assembled by means of threaded connection or by means of snap-fit.

[0049] The base 100 is provided with an ultrasonic atomizing chamber 101, and an ultrasonic atomizer 120 is provided in the ultrasonic atomizing chamber 101. The ultrasonic atomizer 120 operates to atomize the water in the ultrasonic atomizing chamber 101 into water mist, which is then sprayed into the air to increase the air humidity.

[0050] The upper body 200 is provided with a water storage chamber 201, which mainly serves to store water.

[0051] The ultrasonic atomizing chamber 101 and the water storage chamber 201 are connected by a fluid channel 202. Water from the water storage chamber 201 flows into the ultrasonic atomizing chamber 101 through the fluid channel 202. A two-way piston valve 300 is provided corresponding to the fluid channel 202. The two-way piston valve 300 mainly controls the opening and closing of the fluid channel 202.

[0052] The bidirectional piston valve 300 includes: a valve stem 310, an upper valve plate 320, a lower valve plate 330, a spring 340, and a float 350; the upper valve plate 320 and the lower valve plate 330 are mounted on the valve stem 310 and face away from each other; the spring 340 is sleeved on the valve stem 310 and located between the upper valve plate 320 and the lower valve plate 330, and the spring 340 provides the force for the valve stem 310 to move downward in the fluid channel 202; the float 350 is disposed at the end of the valve stem 310; after the upper body 200 is assembled on the base 100, the float 350 is located in the ultrasonic atomization chamber 101.

[0053] like Figure 4 and Figure 5 As shown, the upper body 200 is removed from the base 100. Under the elastic force of the spring 340, the valve stem 310 tends to move downward, causing the upper valve plate 320 to abut against the upper end of the fluid channel 202. The upper end of the fluid channel 202 is closed. At this time, water is injected into the water storage chamber 201, and the water is stored in the water storage chamber 201 and will not flow out through the fluid channel 202.

[0054] like Figure 6-7 As shown, after the upper body 200 is assembled onto the base 100, the valve stem 310 is lifted and moved upward. Neither the upper valve plate 320 nor the lower valve plate 330 abuts against the upper and lower ends of the fluid channel 202. The fluid channel 202 connects the water storage chamber 201 and the ultrasonic atomizing chamber 101. Water from the water storage chamber 201 flows into the ultrasonic atomizing chamber 101 through the fluid channel 202.

[0055] like Figure 8-9As shown, when the water level in the ultrasonic atomizing chamber 101 reaches a certain height, the float 350 rises under the action of buoyancy, which pushes the valve stem 310 to move upward. The lower valve plate 330 abuts against the lower end of the fluid channel 202, and the lower end of the fluid channel 202 is closed, so the water storage chamber 201 and the ultrasonic atomizing chamber 101 are no longer connected. When the water level in the ultrasonic atomizing chamber 101 drops, the position of the float 350 will change with the height of the water level. After the water level drops, the float 350 drops, and the valve stem 310 moves downward. The fluid channel 202 connects the water storage chamber 201 and the ultrasonic atomizing chamber 101, and the water in the water storage chamber 201 flows into the ultrasonic atomizing chamber 101 through the fluid channel 202.

[0056] Furthermore, both the upper valve plate 320 and the lower valve plate 330 are arranged in an umbrella shape. This shape allows the upper valve plate 320 to be effectively pressed against the upper end of the fluid channel 202, and the lower valve plate 330 to be effectively pressed against the lower end of the fluid channel 202, resulting in good sealing stability.

[0057] The upper valve plate 320 is located inside the water storage chamber 201; the lower valve plate 330 is located inside the ultrasonic atomization chamber 101.

[0058] Furthermore, a circular annular plate 203 is provided in the fluid channel 202, and the periphery of the circular annular plate 203 is partially connected to the inner wall of the fluid channel 202.

[0059] The valve stem 310 passes through the center of the annular plate 203;

[0060] One end of the spring 340 is supported on the lower bottom surface of the annular plate 203, and the other end is supported on the lower valve plate 330, which enables the spring 340 to provide the force for the valve stem 310 to move downward;

[0061] The diameter of the upper end of the valve stem 310 is larger than the central hole diameter of the annular plate 203; after the float 350 is installed at the lower end of the valve stem 310, its diameter is also larger than the central hole diameter of the annular plate 203, so that the valve stem 310 will not detach from the fluid channel 202.

[0062] In one embodiment, after the upper body 200 is assembled onto the base 100, the float 350 abuts against the inner bottom wall of the ultrasonic atomizing cavity 101;

[0063] Specifically, after water is filled into the upper body 200, the upper body 200 is assembled into the base 100, the float 350 abuts against the inner bottom wall of the base 100, causing the valve stem 310 to rise, the fluid channel 202 to open, and the water in the water storage chamber 201 flows into the ultrasonic atomizing chamber 101 through the fluid channel 202.

[0064] The distance by which the valve stem 310 rises is such that the upper valve plate 320 moves away from the upper end of the fluid channel 202, while the lower valve plate 330 does not press against the lower end of the fluid channel 202.

[0065] The float 350 rises as the water level in the ultrasonic atomization chamber 101 rises. When the water level reaches the set height, the float 350 moves upward under the action of buoyancy, causing the lower valve plate 330 to abut against the lower end of the fluid channel 202.

[0066] Furthermore, the distance between the upper valve plate 320 and the lower valve plate 330 is greater than the distance from the upper end to the lower end of the fluid channel 202.

[0067] In one embodiment, the ultrasonic atomizing chamber 101 is provided with a top post 110 below the float 350, and the top post 110 corresponds to the float 350 to lift the valve stem 310.

[0068] Specifically, after water is injected into the upper body 200, the upper body 200 is assembled onto the base 100, the float 350 abuts against the top column 110, causing the valve stem 310 to rise, the fluid channel 202 to open, and the water in the water storage chamber 201 flows into the ultrasonic atomizing chamber 101 through the fluid channel 202.

[0069] The distance by which the valve stem 310 rises is such that the upper valve plate 320 moves away from the upper end of the fluid channel 202, while the lower valve plate 330 does not press against the lower end of the fluid channel 202.

[0070] The float 350 rises as the water level in the ultrasonic atomization chamber 101 rises. When the water level reaches the set height, the float 350 moves upward under the action of buoyancy, causing the lower valve plate 330 to abut against the lower end of the fluid channel 202.

[0071] It should be noted that: due to the action of the float 350 against the inner bottom wall of the base 100, or due to the action of the float 350 against the top column 110, after the upper body 200 is installed on the base 100, the upper valve plate 320 is always in a state away from the upper end of the fluid channel 202; only when the upper body 200 is removed from the base 100 will the upper valve plate 320 close the upper end of the fluid channel 202 when the valve rod 310 moves down.

[0072] In one embodiment, the upper body 200 includes: a bottom shell 210 with an atomizing channel 211 and an upper shell 220; the atomizing channel 211 is connected to the ultrasonic atomizing chamber 101; water mist generated by the ultrasonic atomizer 120 enters the atomizing channel 211;

[0073] Here, the ultrasonic atomizer 120 adopts existing technology, and the specific structure and principle of the ultrasonic atomizer 120 will not be described here.

[0074] Furthermore, the top of the upper shell 220 is provided with a cover 230. Water can be injected into the water storage chamber 201 by removing or opening the cover 230. The cover 230 is provided with a mist outlet 240. The atomizing channel 211 is connected to the mist outlet 240, and the water mist is finally sprayed out from the mist outlet 240.

[0075] Optionally, a water storage cavity 201 may be formed between the upper shell 220 and the cover 230, or a water storage cavity may be constructed inside the upper shell 220 or a water tank may be installed.

[0076] Furthermore, the fluid channel 202 is formed in the bottom shell 210.

[0077] In one embodiment, the base 100 has an installation cavity 102 below the ultrasonic atomizing cavity 101; a PCB board 130 is installed in the installation cavity 102; the ultrasonic atomizer 120 is electrically connected to the PCB board 130; the base 100 may also be provided with a control board, etc., which is electrically connected to the PCB board 130, and controls the operation of the humidifier through the control board.

[0078] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0079] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
