Description

Technical Field

[0001] This utility model relates to the field of humidifiers, and in particular to a water injection structure for a 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. If the two can be combined into one, the structure of the humidifier can be improved so that the two types of humidifiers can share some components, thereby avoiding redundant settings and increasing product costs. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned technical problems and provide a water injection structure for a composite humidifier. This application aims to enable the atomizer and the wet curtain to be injected with water through the same water injection structure.

[0006] A water filling structure for a composite humidifier includes a main unit, a water tank, a water pump, an atomizing water tank, an atomizing plate, an overflow pipe, and a wet curtain. The atomizing water tank and the atomizing plate are installed in the main unit. The water inlet of the water pump is connected to the water tank. The atomizing water tank has a water inlet, and the water outlet of the water pump is connected to the water inlet. The upper end of the overflow pipe is located in the atomizing water tank, and the upper end of the overflow pipe is higher than the bottom surface of the atomizing water tank. The bottom cover of the main unit has a perforation, and the lower end of the overflow pipe is connected to the outside of the main unit through the perforation. The wet curtain is located in the water tank, and the main unit is installed on the water tank so that the lower end of the overflow pipe is opposite to the wet curtain. Water is injected into the atomizing water tank by the water pump, and the water in the atomizing water tank overflows the overflow pipe and injects water into the wet curtain.

[0007] According to the water filling structure of the composite humidifier of this application, water is filled into the atomizing water tank and the wet curtain by a water pump, which avoids the repetitive setting of the water filling structure of the composite humidifier, which helps to reduce the cost of the composite humidifier and makes the structure of the composite humidifier more compact. In addition, due to the existence of the overflow pipe, the water level of the atomizing water tank can always be maintained at the height of the overflow pipe, and the water pump will not fill the atomizing water tank with too much water. The wet curtain of this application can also play a role in silencing the noise and prevent the overflow pipe from dripping directly into the water tank and making a dripping sound.

[0008] Furthermore, it also includes a water pump housing, which mates with the inner wall of the water tank to form a water pump chamber. The water pump is installed inside the water pump chamber, with its inlet end extending out of the housing and its outlet end connected upwards to a water supply port formed at the top of the housing. The water inlet is connected to the water supply port. The water supply port formed by the water pump housing facilitates the formation of a stable water supply pipeline within the disassembly structure of the main unit and the water tank.

[0009] Furthermore, the bottom cover of the main unit is equipped with a water supply plug, which is connected to the water inlet. When the main unit is installed on the water tank, the water supply plug and the water inlet are plugged into each other. Through the plugging and unplugging of the water supply plug and the water inlet, a stable water supply pipeline is formed in the disassembled structure of the main unit and the water tank.

[0010] Furthermore, the main unit and the water tank are detachably installed. The bottom cover is equipped with a power supply socket, and the top of the water pump housing forms a power supply plug. The power supply socket and the power supply plug are plugged in to electrically connect the main unit and the water pump. The water pump housing can also easily form the electrical connection structure of the water pump, thereby avoiding the need to set up a separate power supply for the water pump in the water tank, and facilitating the main unit to supply power to the water pump and control its operation.

[0011] Furthermore, the evaporative cooling pad is positioned to avoid obstructing the water pump housing, and the top of the evaporative cooling pad is lower than the top of the water pump housing. This prevents the evaporative cooling pad from interfering with the assembly / disassembly structure between the main unit and the water tank.

[0012] Furthermore, the water tank is equipped with a support frame, the wet curtain is installed on the support frame, and the lower part of the wet curtain is the water storage chamber of the water tank.

[0013] Furthermore, it also includes a wet curtain fan, which is installed in the main unit. The bottom cover has a first air inlet, which is opposite to the air inlet end of the wet curtain fan. Installing the wet curtain fan on the main unit avoids increasing the weight of the water tank by installing it inside, making it more convenient for users to add water to the tank.

[0014] Furthermore, the evaporative cooling pad is annular, and the side wall of the water tank is provided with a second air inlet. The second air inlet faces the outer surface of the evaporative cooling pad, and the first air inlet faces the middle of the evaporative cooling pad. Outside air enters the humidifier through the second air inlet and is blown towards the evaporative cooling pad. As it passes through the evaporative cooling pad, it carries away the moisture on the pad, thus becoming humidified air. This humidified air is then drawn into the evaporative cooling pad fan through the first air inlet from the middle of the pad, and then blown out of the humidifier to humidify the surrounding environment.

[0015] Furthermore, the top of the evaporative cooling pad is equipped with a flow equalization plate, which has multiple flow equalization holes. Water is injected into the flow equalization plate through the overflow pipe, and the water falls evenly onto the evaporative cooling pad through the flow equalization holes. The flow equalization plate facilitates the even distribution of water flowing from the overflow pipe onto the evaporative cooling pad.

[0016] Furthermore, it also includes a control circuit board, which is located inside the main unit, and the water pump is electrically connected to the control circuit board via a power supply socket and a power supply plug. Attached Figure Description

[0025] The water injection structure of a composite humidifier according to this utility model is described in conjunction with the accompanying drawings.

[0026] like Figures 1 to 8The water filling structure of the composite humidifier shown uses a water pump 3 to fill the atomizing water tank 4 and the evaporative cooling pad 7 with water. This avoids the repetitive setup of the water filling structure in the composite humidifier, which helps reduce the cost of the composite humidifier and makes its structure more compact. Specifically, it includes a main unit 1, a water tank 2, a water pump 3, an atomizing water tank 4, an atomizing plate 5, an overflow pipe 6, and an evaporative cooling pad 7. The atomizing water tank 4 and the atomizing plate 5 are installed in the main unit 1. The atomizing plate 5 is an ultrasonic atomizing plate 5 or a heated atomizing plate 5. The water inlet of the water pump 3 is connected to the water tank 2. The atomizing water tank 4 has a water inlet 41, and the water outlet of the water pump 3 is connected to the water inlet 41. The atomizing plate 5 is located on the bottom surface of the atomizing water tank 4. The upper end of the overflow pipe 6 is located on the bottom surface of the atomizing water tank 4 and extends above the bottom surface. The lower end of the overflow pipe 6 extends from the bottom cover 13. The evaporative cooling pad 7... The main unit 1 is installed in the water tank 2, with the lower end of the overflow pipe 6 facing the wet curtain 7. Water is injected into the atomizing water tank 4 by the water pump 3. The water in the atomizing water tank 4 overflows the overflow pipe 6 and injects water into the wet curtain 7. The overflow pipe 6 ensures that the water level in the atomizing water tank 4 is always maintained at the height of the overflow pipe 6, preventing the water pump 3 from injecting too much water into the atomizing water tank 4. The wet curtain 7 of this application also has a silent effect, preventing the overflow pipe 6 from dripping directly into the water tank 2 and making a dripping sound. To facilitate the assembly of the overflow pipe 6, this application divides the overflow pipe 6 into two parts, including an overflow insertion pipe 61 and a long pipe body 62. The overflow insertion pipe 61 is integrally set with the atomizing water tank 4 and extends into the atomizing water tank 4 to form an overflow effect. The overflow insertion pipe 61 extends downward for the long pipe body 62 to be inserted and installed. The long pipe body 62 extends out from the perforation of the bottom cover 13.

[0027] The bottom cover 13 of the main unit 1 is provided with a step 133 on the outside. When the main unit 1 is installed on the water tank 2, the top of the water tank 2 can be fitted onto the step 133, and the top surface of the water tank 2 abuts against the step surface, thereby realizing the detachable installation of the main unit 1 and the water tank 2.

[0028] like Figures 1 to 5 As shown, it also includes a water pump housing 22, which is fixed to the inner wall of the water tank 2 to form a water pump cavity. The water pump housing 22 can be fixedly connected to the inner wall of the water tank 2 by ultrasonic welding. The water pump 3 is installed in the water pump cavity. The water inlet end of the water pump 3 extends out of the water pump housing 22, so that the water pump 3 can draw water from the water tank 2 through the water inlet end. It can also fix the position of the water pump 3 by the water pump housing 22. The water outlet end of the water pump 3 is connected upward through a water pipe to the water supply inlet 221 formed on the top of the water pump housing 22. The water inlet 41 is connected to the water supply inlet 221.

[0029] like Figures 3 to 5As shown, the main unit 1 and the water tank 2 are detachably installed. The bottom cover 13 of the main unit 1 is provided with a water supply plug 131, which is connected to the water inlet 41. When the main unit 1 is installed on the water tank 2, the water supply plug 131 and the water supply inlet 221 are plugged into each other. Since the main unit 1 and the water tank 2 are detachable, if they are only connected by a water pipe, a stable water supply pipeline cannot be formed. By plugging the water supply plug 131 and the water supply inlet 221, a stable water supply pipeline can be formed in the detachable structure of the main unit 1 and the water tank 2.

[0030] like Figures 3 to 5 As shown, the bottom cover 13 is provided with a power supply socket 132, and the top of the water pump housing 22 forms a power supply plug 222. The power supply socket 132 is plugged into the power supply plug 222, so that the host 1 and the water pump 3 are electrically connected. The water pump housing 22 can also easily form an electrical connection structure for the water pump 3, thereby avoiding the need to set up a separate power supply for the water pump 3 in the water tank 2, and making it convenient for the host 1 to supply power to the water pump 3 and control the operation of the water pump 3.

[0031] like Figure 4 and Figure 5 As shown, the wet curtain 7 is provided with a clearance corresponding to the position of the water pump housing 22, and the top of the wet curtain 7 is lower than the top of the water pump housing 22 to avoid the wet curtain 7 affecting the disassembly and assembly structure between the main unit 1 and the water tank 2.

[0032] like Figure 4 and Figure 5 As shown, the water tank 2 is equipped with a bracket 21, and the wet curtain 7 is installed on the bracket 21. The lower part of the wet curtain 7 is the water storage chamber of the water tank 2. The position of the water storage chamber corresponds to the position of the water inlet of the water pump 3. Preferably, the water inlet is located at the bottom of the water storage chamber.

[0033] The system also includes a wet curtain fan 8, which is installed in the main unit 1. A first air inlet 134 is provided on the bottom cover 13, opposite to the air inlet end of the wet curtain fan 8. The main unit 1 is provided with an atomizing air duct 11 and a wet curtain air duct 12 corresponding to the atomizing plate 5 and the wet curtain 7. The atomizing air duct 11 is located in the atomizing water tank 4. The system also includes an outer air duct housing 122, with the wet curtain air duct 12 located between the outer air duct housing 122 and the atomizing water tank 4. A spray nozzle 111 and a wet curtain air outlet 121 are also provided on the outer casing of the main unit 1 corresponding to the atomizing air duct 11 and the wet curtain air duct 12. The system also includes a spray fan 43 and a fan mounting housing 112. The spray fan 43 is located at the bottom of the atomizing water tank 4, and the fan mounting housing 112 surrounds the spray fan 43, separating the spray fan 43 from the wet curtain air duct 12. The spray fan 43 is fixed to the bottom of the atomizing water tank 4 or to the fan mounting housing 112 by screws. The fan mounting housing 112 is also provided with a mounting groove and a limiting plate 113. The wet curtain fan 8 includes a motor 81 and a fan wheel 82. The motor 81 is set in the mounting groove and is fixed to the screw fixing post on the inner side wall of the mounting groove by the limiting plate 113, so that the motor 81 is limited in the mounting groove. The output shaft 811 of the motor 81 passes through the limiting plate 113 and is connected to the fan wheel 82 for transmission. The fan wheel 82 is set in the atomizing air duct 11. A third air inlet 114 is provided at the bottom of the mounting groove. There is a gap between the limiting plate 113 and the outer side wall of the mounting groove, and there is also a gap between the fan wheel 82 and the limiting plate 113. Through these gaps and the third air inlet 114, the spray fan 43 can draw air normally.

[0034] like Figures 1 to 8 As shown, the wet curtain 7 is annular, and the side wall of the water tank 2 is provided with a second air inlet 23. The second air inlet 23 is opposite to the outer side of the wet curtain 7, and the first air inlet 134 is opposite to the middle of the wet curtain 7. The air outside the composite humidifier will enter through the second air inlet 23 and blow towards the wet curtain 7. When passing through the wet curtain 7, it can take away the water vapor on the wet curtain 7, thus becoming humid air. The humid air is drawn into the wet curtain fan 8 from the middle of the wet curtain 7 through the first air inlet 134. The wet curtain fan 8 blows the humid air out of the composite humidifier from the wet curtain outlet 121 along the wet curtain air duct 12 to humidify the surrounding environment. The spray fan 43 blows air into the atomizing air duct 11, so that the mist generated by the atomizing plate 5 can be sprayed out from the spray nozzle 111.

[0035] like Figures 4 to 6As shown, the top of the wet curtain 7 is provided with a flow equalization plate 71, and the flow equalization plate 71 is provided with a plurality of flow equalization holes 711. The overflow pipe 6 injects water into the flow equalization plate 71, and the water falls evenly onto the wet curtain 7 through the flow equalization holes 711. When the overflow pipe 6 injects water into the wet curtain 7, the water will first remain on the flow equalization plate 71 under the action of the flow equalization holes 711. When the water volume can overflow the flow equalization holes 711, it can flow evenly to the wet curtain 7 through the flow equalization holes 711.

[0036] It also includes a control circuit board 9, which is installed inside the host 1. The water pump 3 is electrically connected to the control circuit board 9. Specifically, the control circuit board 9 is electrically connected to the water pump 3 through the power supply socket 132 and the power supply plug 222.
