Description

Technical Field

[0001] This utility model relates to the field of humidifiers, and in particular to a multi-mode composite humidifier. Background Technology

[0002] In daily life and industrial environments, humidifiers, as key devices for regulating air humidity, are widely used in homes, offices, hospitals, laboratories, and various industrial sites. They play an important role in improving indoor environmental comfort, maintaining human health, and protecting precision equipment. Based on different humidification principles and effects, the mainstream humidifiers on the market are mainly divided into two categories: mist-generating humidifiers and mist-free humidifiers.

[0003] Mist-type humidifiers operate on the principle of ultrasonic vibration technology, with a transducer as their core component. Driven by electrical energy, the transducer generates high-frequency vibrations. This vibrational energy acts on the water surface, breaking down water molecules into tiny water vapor particles. Subsequently, through a built-in air duct system, these water vapor particles are dispersed and evenly distributed into the air, forming a visible mist that provides users with an intuitive and rapid humidification experience. Mist-free humidifiers employ a different humidification mechanism. They typically use a water pump to circulate and spray water onto a specially designed wet curtain or filter. The wet curtain material has excellent water absorption and evaporation properties; when air passes through the wet curtain, the moisture naturally evaporates, releasing humidified air.

[0004] Given the advantages and limitations of the two types of humidifiers, there is a certain market demand for a composite humidifier that can provide both mist humidification and mist-free humidification functions. However, current technology lacks a composite humidifier that can be started independently or in combination with mist-free humidification. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned technical problems and provide a composite humidifier with multiple working modes. This application is to provide a composite humidifier with multiple working modes.

[0006] A multi-mode composite humidifier includes a water tank, an atomizing component, a wet curtain component, and a water supply component for supplying water from the water tank to the wet curtain component and the atomizing component; the multi-mode operation includes a mist-generating humidification mode in which the atomizing component is activated alone, a mist-free humidification mode in which the wet curtain component is activated alone, and a composite mode combining mist-generating and mist-free operation in which the atomizing component and the wet curtain component are activated simultaneously.

[0007] According to the multi-mode composite humidifier of this application, water is supplied to the wet curtain assembly and the atomizing assembly through a water tank and a water supply assembly, so that the wet curtain assembly and the atomizing assembly can perform humidification work normally. The wet curtain assembly and the atomizing assembly are independent of each other but can cooperate with each other, forming a mist humidification working mode, a mist-free humidification working mode, and a composite working mode combining mist and mist-free modes.

[0008] Furthermore, the atomizing component includes an atomizing chamber and an overflow pipe; the water supply component includes a water pump; the inlet of the water pump is connected to a water tank, the outlet of the water pump is connected to the atomizing chamber, and the overflow pipe connects the atomizing chamber and the evaporative cooling pad assembly. The inlet of the overflow pipe is higher than the bottom surface of the atomizing chamber, and the water in the atomizing chamber overflows the inlet of the overflow pipe and flows along the overflow pipe to the evaporative cooling pad assembly. By using a single water pump and overflow pipe to supply water to both the atomizing component and the evaporative cooling pad assembly, multiple operating modes of the composite humidifier are achieved, avoiding the need for redundant water pump settings.

[0009] Furthermore, the water supply component includes a water level sensor; the water level sensor is used to detect the water level in the atomizing chamber; in the mist humidification working mode and the combined working mode, when the water level sensor detects that the water level in the atomizing chamber is lower than the minimum water level, the water supply pump is started. When the atomizing component is started for humidification, since the atomizing component needs to maintain a water supply to work normally, the water level sensor in the water supply component is used to detect the water level in the atomizing chamber, so that the water pump can be started to replenish water when there is a water shortage, ensuring that the atomizing component will not be damaged due to water shortage. When only the wet curtain component is working, since the atomizing component does not need to be started, there is no need to detect the water level. The water pump can be started directly to inject water into the atomizing component, so that the water flows into the wet curtain component through the overflow pipe, allowing the wet curtain to perform normal mist-free humidification.

[0010] Furthermore, the atomizing assembly includes an atomizing plate, and the atomizing plate, water level sensor, and overflow pipe are disposed on the bottom surface of the atomizing chamber. The water level sensor is positioned away from the overflow pipe. This avoids the water level sensor being agitated by the water flow around the overflow pipe, which could cause false readings.

[0011] Furthermore, the evaporative cooling pad assembly includes an evaporative cooling pad and an evaporative cooling pad fan. An evaporative cooling pad support is provided inside the water tank. The evaporative cooling pad is placed on the support and faces the outlet of the overflow pipe. The evaporative cooling pad fan is located in an air duct communicating with the evaporative cooling pad. Below the support is the water storage chamber of the water tank, and the inlet of the water supply pump is connected to the water storage chamber. This ensures that the evaporative cooling pad is not directly immersed in water, and that when the flow rate of water from the overflow pipe is too high, it will flow back into the water storage chamber of the water tank under gravity.

[0012] Furthermore, the evaporative cooling pad assembly also includes a distribution plate with multiple distribution holes. The outlet of the overflow pipe is connected to the distribution plate, and the distribution plate is connected to the evaporative cooling pad through the distribution holes. The distribution plate enables the evaporative cooling pad to be more evenly wetted, thereby improving the humidification effect of the evaporative cooling pad.

[0013] Furthermore, the atomizing component is connected to a spray nozzle, and the evaporative cooling pad assembly is connected to an evaporative cooling pad air outlet, with the evaporative cooling pad air outlet arranged around the spray nozzle.

[0014] Furthermore, the atomizing component also includes an atomizing fan, and the evaporative cooling pad component includes an evaporative cooling pad fan. In the mist-containing humidification mode, the atomizing fan blows air into the spray nozzle; in the mist-free humidification mode, the evaporative cooling pad fan blows air into the evaporative cooling pad outlet; in the combined mode, both the atomizing fan and the evaporative cooling pad fan are activated simultaneously, and in the combined mode, the airflow velocity at the evaporative cooling pad outlet is greater than the airflow velocity at the spray nozzle. By setting the wind speed and positional relationship, in the mode where both the atomizing component and the evaporative cooling pad component are humidifying simultaneously, the evaporative cooling pad component can help the atomizing component blow the mist higher and diffuse it over a wider area, avoiding the problem of excessively high local humidity around the humidifier.

[0015] Furthermore, it also includes a blower, which is connected to both the spray nozzle and the wet curtain air outlet, and the blower is activated to blow air in any working mode.

[0016] Furthermore, the water supply assembly includes an atomizing water pump and a wet curtain water pump. The atomizing water pump and the wet curtain water pump supply water from the water tank to the atomizing assembly and the wet curtain assembly, respectively. In the mist-containing humidification mode, only the atomizing water pump is activated; in the mist-free humidification mode, only the wet curtain water pump is activated; and in the combined mode, both the atomizing water pump and the wet curtain water pump are activated simultaneously. By supplying water to the atomizing assembly and the wet curtain assembly separately using two pumps, the malfunction of one pump can prevent the other humidification assembly from failing to function properly.

[0024] The present invention relates to a multi-mode composite humidifier, described in conjunction with the accompanying drawings.

[0025] like Figures 1 to 7 The illustrated multi-mode humidifier includes a water tank 1, an atomizing component 2, a wet curtain component 3, and a water supply component for supplying water from the water tank 1 to the wet curtain component 3 and the atomizing component 2. The multiple operating modes include a misting humidification mode where the atomizing component 2 operates alone, a mist-free humidification mode where the wet curtain component 3 operates alone, and a combined misting and mist-free operating mode where both the atomizing component 2 and the wet curtain component 3 operate simultaneously. Thus, by supplying water to the wet curtain component 3 and the atomizing component 2 through the water tank 1 and the water supply component, the wet curtain component 3 and the atomizing component 2 can perform humidification operations normally. The wet curtain component 3 and the atomizing component 2 are independent yet can cooperate with each other, forming a misting humidification mode, a mist-free humidification mode, and a combined misting and mist-free operating mode.

[0026] As shown in the accompanying drawings of this application, the drawings disclose an embodiment in which water is supplied to both the atomizing component 2 and the evaporative cooling pad component 3 simultaneously using the same water supply pump 4, thereby realizing multiple working modes of the composite humidifier. The atomizing component 2 is provided with an atomizing chamber 21 and an overflow pipe 6. The water supply component includes a water supply pump 4, the inlet of which is connected to a water tank 1, and the outlet of which is connected to the atomizing chamber 21. The overflow pipe 6 connects the atomizing chamber 21 and the evaporative cooling pad component 3. The inlet of the overflow pipe 6 is higher than the bottom surface of the atomizing chamber 21. The water supply pump 4 injects water into the atomizing component 2. When the water overflows the inlet of the overflow pipe 6, it flows along the overflow pipe 6 to the evaporative cooling pad component 3, thus realizing the injection of water into both the atomizing component 2 and the evaporative cooling pad component 3 using a single water supply pump 4.

[0027] Both the atomizing component 2 and the evaporative cooling pad component 3 require water to function properly. The atomizing component 2, in particular, will suffer damage if it operates without water, resulting in the loss of its atomizing function. Preferably, the water supply component also includes a water level sensor 5, which detects the water level in the atomizing chamber 21. In the mist-containing humidification mode and the combined working mode, the atomizing component 2 is activated. The water supply component detects the water level in the atomizing chamber 21 via the water level sensor 5. When the water level sensor 5 detects that the water level in the atomizing chamber 21 is below the minimum water level (i.e., the water level in the atomizing chamber 21 cannot meet the minimum water level required for the atomizing component 2 to operate safely), it activates the water supply pump 4. In the non-mist humidification mode, since the atomizing component 2 is not working and only the evaporative cooling pad component 3 is working, the water supply component directly activates the water supply pump 4 to inject water into the atomizing component 2 without relying on the detection signal from the water level sensor 5.

[0028] The water supply assembly also includes a main control circuit board 8, which is electrically connected to the atomizing assembly 2, the wet curtain assembly 3, the water supply pump 4, and the water level sensor 5, thereby facilitating their control.

[0029] like Figures 1 to 6 As shown, the composite humidifier also includes a main unit 7. The outer casing of the main unit 7 includes a top cover 71 and a bottom cover 72. The side of the bottom cover 72 is provided with a mounting step 723. The main unit 7 is detachably mounted on the water tank 1 via the mounting step 723. The top surface of the water tank 1 abuts against the step surface of the mounting step 723. The atomizing component 2 is disposed inside the outer casing of the main unit 7. The atomizing component 2 also includes an atomizing plate 22 and an atomizing fan 23. The bottom surface of the atomizing chamber 21 is provided with a water inlet 211. The water supply pump 4 connects to the water inlet 211 to inject water into the atomizing chamber 21. The atomizing plate 22 is also... Installed on the outer bottom of the atomizing chamber 21, the atomizing plate 22 is connected to the atomizing chamber 21, so that the water in the atomizing chamber 21 is atomized to produce mist. A blower 212 extends into the atomizing chamber 21. The atomizing fan 23 is installed on the outer bottom of the atomizing chamber 21 and blows the mist out of the atomizing chamber 21 through the blower 212. The upper ends of the water level sensor 5 and the overflow pipe 6 are also set on the bottom surface of the atomizing chamber 21. Since water flow will be generated around the upper opening of the overflow pipe, the water flow may affect the water level sensor 5's detection of the water level. Therefore, the water level sensor 5 is set at a position away from the overflow pipe 6.

[0030] like Figures 1 to 6As shown, the evaporative cooling pad assembly 3 includes an evaporative cooling pad 31 and an evaporative cooling pad fan 32. An evaporative cooling pad support 12 is provided in the water tank 1, and the evaporative cooling pad 31 is placed on the support 12. Below the support 12 is the water storage chamber of the water tank 1. The inlet of the water pump 4 is connected to the water storage chamber. A first air inlet 11 is provided on the side of the water tank 1 corresponding to the evaporative cooling pad 31. The evaporative cooling pad fan 32 is installed at the bottom of the main unit 7, and a second air inlet 724 is provided on the bottom cover 72. The second air inlet 724 is connected to the evaporative cooling pad fan. With the air inlets of 32 facing each other, when the main unit 7 is installed on the water tank 1, air can be guided through the wet curtain 31. The lower end of the overflow pipe 6 extends out of the bottom cover 72. The wet curtain 31 is located at the lower end of the overflow pipe 6, so that the water flowing down the overflow pipe 6 can flow onto the wet curtain 31. The wet curtain assembly 3 also includes a duct housing 33, which surrounds the atomizing assembly 2, thereby forming a wet curtain duct between the duct housing 33 and the atomizing assembly 2. The wet curtain fan 32 is located in the wet curtain duct.

[0031] Preferred options Figure 6 and Figure 7 As shown, the wet curtain assembly 3 also includes a distribution plate 34, which is disposed on the upper part of the wet curtain 31. The distribution plate 34 is provided with a plurality of distribution holes 341. The outlet of the overflow pipe 6 is connected to the distribution plate 34. The distribution plate 34 is connected to the wet curtain 31 through the distribution holes 341. When water flows down from the overflow pipe 6, it will first fall onto the distribution plate 34. Under the action of the distribution holes 341, the water will first remain on the distribution plate 34. When the water overflows the distribution holes 341, the water will flow evenly from the distribution holes 341 to the wet curtain 31.

[0032] like Figures 1 to 6 As shown, the atomizing component 2 has a spray nozzle 711, and the evaporative cooling pad component 3 has an evaporative cooling pad air outlet 712. Both the spray nozzle 711 and the evaporative cooling pad air outlet 712 are located on the top cover 71 of the main unit 7. The evaporative cooling pad air outlet 712 is arranged around the spray nozzle 711, and the air velocity of the evaporative cooling pad air outlet 712 is greater than that of the spray nozzle 711. Through the setting of air velocity and position, in the combined working mode, the evaporative cooling pad component 3 can help the atomizing component 2 blow the mist higher and diffuse it to a wider range, avoiding the problem of excessively high local humidity around the humidifier. The arrangement of the evaporative cooling pad air outlet 712 around the spray nozzle 711 includes both a complete ring shape and a ring shape with a certain arc, such as a semicircle or a quarter circle.

[0033] like Figure 1As shown, the water level sensor 5 includes a sensing element 51 and a float 52. A mounting base for the sensing element 51 is provided on the bottom surface of the atomizing chamber 21. The sensing element 51 is installed in the mounting base from the outside of the atomizing chamber 21, and the float 52 is sleeved on the mounting base from the inside of the atomizing chamber 21. The float 52 floats up and down in the atomizing assembly 2 with the water level. The sensing element 51 and the float 52 cooperate to sense the water level in the atomizing assembly 2. Preferably, the sensing element 51 is a Hall effect device, and the float 52 is a float with a magnet.

[0034] like Figures 1 to 6 As shown, the water pump 4 is directly installed in the water storage chamber of the water tank 1, and also includes a pump housing 41. The pump housing 41 is fixed on the inner side of the water tank 1. The top surface of the pump housing 41 forms a water supply port 411 and a power supply plug 412. The bottom cover 72 of the main unit 7 forms a water supply plug 721 and a power supply port 722. The water supply plug 721 is connected to the water inlet 211 of the atomizing chamber 21. When the main unit 7 is installed on the water tank 1, the water supply plug 721 is plugged into the water supply port 411, so that the water outlet of the water pump 4 is connected to the water inlet 211 of the atomizing chamber 21, so that the water pump 4 can inject water into the atomizing chamber 21. The power supply port 722 and the power supply plug 412 are plugged into, thus forming an electrical connection structure between the main unit 7 and the water tank 1, so that the water pump 4 can maintain an electrical connection with the main unit 7.

[0035] This application also provides another embodiment using a single fan, which further includes a blower fan that is simultaneously connected to both the spray nozzle 711 and the wet curtain outlet 712, with the wet curtain outlet 712 also positioned around the spray nozzle 711. The blower fan is activated in any operating mode. For example, if the blower fan is only installed in the wet curtain duct, its activation guides air through the wet curtain 31 and out through the wet curtain outlet 712. A bypass ventilation duct is provided at the outlet end of the blower fan, connecting the wet curtain duct and the atomizing chamber 21. This bypass ventilation duct guides the air blown by the blower fan into the atomizing chamber 21, thereby blowing the mist generated in the atomizing chamber 21 out through the spray nozzle 711. Because the blower is directly installed in the wet curtain duct, the degree of air obstruction in the wet curtain duct is lower than that in the atomization chamber 21. Therefore, the wind speed blown out through the wet curtain outlet 712 is higher than that blown out through the spray nozzle 711. Thus, the wind blown out through the wet curtain outlet 712 can accelerate the mist blown out through the spray nozzle 711, making the mist blow higher and diffuse to a greater distance around the humidifier.

[0036] This application also provides another embodiment in which water is supplied to the atomizing component 2 and the evaporative cooling pad component 3 by means of dual water pumps. The water supply components include an atomizing water pump and an evaporative cooling pad water pump. The atomizing water pump and the evaporative cooling pad water pump supply water from the water tank 1 to the atomizing component 2 and the evaporative cooling pad component 3, respectively. In the mist humidification mode, only the atomizing water pump is activated. In the non-mist humidification mode, only the evaporative cooling pad water pump is activated. In the combined mode, both the atomizing water pump and the evaporative cooling pad water pump are activated simultaneously.

[0037] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
