Description

Technical Field

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

[0002] With the rapid development of modern society and the continuous improvement of people's living standards, people's pursuit of quality of life is increasing, especially in terms of living environment, where the demand for air humidity regulation is becoming more and more significant. Suitable indoor humidity can not only improve living comfort, but also effectively improve respiratory health and protect furniture and decorations from dry damage. Therefore, environmental humidity regulation technology has become an important part of home life.

[0003] Currently, ambient humidity is mainly controlled by humidifiers, with two main types: mist-generating humidifiers and mist-free humidifiers. These two types of humidifiers each have their own characteristics, meeting the needs of different consumers.

[0004] Mist-type humidifiers operate on the principle of ultrasonic technology, with their core component being a transducer. Driven by electrical energy, the transducer vibrates, breaking down water into tiny to micron-sized water vapor particles. These particles are then dispersed into the air through a built-in airflow system, forming a visible mist that rapidly increases humidity. Mist-free humidifiers, on the other hand, use a different principle. They use a water pump to spray water onto a wet curtain. The moisture on the curtain's surface evaporates under the influence of airflow, releasing invisible humidified air and thus increasing indoor humidity.

[0005] Given the respective advantages and limitations of both types of humidifiers, there is a certain market demand for hybrid humidifiers that can simultaneously provide both mist-based and mist-free humidification functions. However, currently, hybrid humidifiers integrating mist and mist-free humidification operate relatively independently. During operation, the water vapor particles generated by mist generation are continuously blown into the air, easily causing excessively high humidity in localized areas. Water accumulation easily forms on the floor around the humidifier and on the surface where it is placed, especially during prolonged operation. This not only affects aesthetics but may also pose safety hazards, such as increased risk of slipping and damage to electrical equipment due to moisture. Therefore, how to reduce or avoid these problems while maintaining effective humidification in hybrid humidifiers has become a pressing technical challenge in the design and improvement of current hybrid humidifiers. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned technical problems and provide a composite humidifier. This application is to improve the structure of the composite humidifier.

[0007] A composite humidifier includes a main unit, a water tank, an atomizing component, a wet curtain component, and a water pump component. The main unit has an atomizing chamber and a wet curtain duct chamber. The first side of the main unit has a spray nozzle and a wet curtain air outlet that connect the atomizing chamber and the wet curtain duct chamber, respectively. The wet curtain air outlet is arranged around the spray nozzle. The water pump component supplies water from the water tank into the wet curtain component and the atomizing chamber. The atomizing component generates mist in the atomizing chamber. The mist is blown out from the spray nozzle. Air passes through the wet curtain component and the wet curtain duct chamber and is blown out from the wet curtain air outlet.

[0008] According to the composite humidifier of this application, a spray nozzle and a wet curtain air outlet are formed on the main unit, respectively blowing out mist and blowing out humidified air passing through the wet curtain. The two are relatively independent. The composite humidifier can be turned on with mist humidification or without mist humidification individually, or it can be turned on with mist humidification and without mist humidification simultaneously. When the mist humidification and without mist humidification functions are turned on simultaneously, due to the position setting of the wet curtain air duct cavity and the wet curtain air outlet relative to the atomizing cavity and the spray nozzle, the air blown out of the wet curtain air outlet can guide and diffuse the mist blown out of the spray nozzle, so that the mist can diffuse faster and farther, avoiding the accumulation around the humidifier and causing the humidifier to have excessive humidity.

[0009] Furthermore, the evaporative cooling pad assembly includes an evaporative cooling pad, and the water pump assembly includes a water supply pump and an overflow pipe. The inlet of the water supply pump is connected to a water tank, and the outlet of the water supply pump is connected to an atomizing chamber. The overflow pipe connects the atomizing chamber and the evaporative cooling pad. The water supply pump injects water into the atomizing chamber, and the water level in the atomizing chamber overflows the upper opening of the overflow pipe and flows along the overflow pipe to the evaporative cooling pad. By simultaneously injecting water into the atomizing chamber and the evaporative cooling pad by the water supply pump, the structure of the composite humidifier becomes more compact. When the overflow pipe injects water into the atomizing chamber, the water level in the atomizing chamber can always be maintained at the same height as the upper opening of the overflow pipe.

[0010] Furthermore, the main unit includes an atomizing housing and a wet curtain duct housing. The atomizing chamber is formed within the atomizing housing, and the wet curtain duct housing surrounds the atomizing housing. The wet curtain duct cavity is formed between the atomizing housing and the wet curtain duct housing. An extension extending out of the wet curtain duct housing is provided on one side of the atomizing housing, and a water inlet is provided in the extension, which is connected to the outlet of a water pump. The extension facilitates the pump's injection of water into the atomizing chamber.

[0011] Furthermore, the atomizing housing includes a motor mounting base, and the wet curtain assembly also includes a wet curtain fan. The wet curtain fan includes a motor and a fan wheel. The motor is fixed on the motor mounting base, and the output shaft of the motor passes through the motor mounting base and extends into the wet curtain air duct cavity. The fan wheel is fixed on the output shaft in the wet curtain air duct cavity.

[0012] Furthermore, the second side of the main unit has a first air inlet, which is opposite to the air inlet of the wet curtain fan. The wet curtain is annular and is installed in a water tank. The water tank has a second air inlet, which is opposite to the side of the wet curtain. The main unit is detachably mounted on the water tank via the second side, so that the middle part of the wet curtain is opposite to the first air inlet.

[0013] Furthermore, the water pump assembly also includes a water pump housing, which cooperates with the inner wall of the water tank to form a water pump cavity. The water supply pump is installed in the water pump cavity, with the water inlet of the water supply pump extending out of the water pump housing and the water outlet of the water supply pump connected upward to a water supply socket formed on the top of the water pump housing. A power supply plug is also formed on the top of the water pump housing.

[0014] Furthermore, the main unit is provided with a mounting surface that can be detachably installed with the water tank. A water supply plug and a power supply socket are formed on the mounting surface. The water supply plug is connected to the atomizing chamber. The main unit is installed on the water tank so that the water supply plug is plugged into the water supply socket and the power supply plug is plugged into the power supply socket.

[0015] Furthermore, the wet curtain assembly also includes a wet curtain fan, which is disposed in the wet curtain air duct cavity. The atomizing assembly includes an atomizing fan, which guides air through the wet curtain and blows it out from the wet curtain air outlet. The atomizing fan blows air into the atomizing cavity and blows the mist out from the spray nozzle.

[0016] Furthermore, the main unit also includes a bypass ventilation duct, and the evaporative cooling pad assembly includes an evaporative cooling pad fan. The evaporative cooling pad fan is disposed in the evaporative cooling pad duct cavity, which is connected to the atomizing chamber via the bypass ventilation duct. The evaporative cooling pad fan guides air through the evaporative cooling pad; part of the air is blown out from the evaporative cooling pad outlet, and the other part of the air is blown into the atomizing chamber through the bypass ventilation duct, thereby blowing the mist out from the spray nozzle. This alternative blowing solution provided in this application avoids the need to install a fan in the atomizing assembly, reducing costs.

[0017] Furthermore, the water pump assembly includes an atomizing water pump and an evaporative cooling pad water pump. The inlet of the atomizing water pump is connected to a water tank, the outlet of the atomizing water pump is connected to an atomizing chamber, the inlet of the evaporative cooling pad water pump is connected to a water tank, and the outlet of the evaporative cooling pad water pump is connected to the evaporative cooling pad assembly.

[0026] The present invention relates to a composite humidifier, as illustrated in the accompanying drawings.

[0027] like Figures 1 to 8 The illustrated composite humidifier includes a main unit 1, a water tank 2, an atomizing assembly 3, a wet curtain assembly 4, and a water pump assembly 5. The main unit 1 contains an atomizing chamber 12 and a wet curtain duct chamber 13. The first surface 11 of the main unit 1 has a spray nozzle 111 and a wet curtain air outlet 112 connecting the atomizing chamber 12 and the wet curtain duct chamber 13, respectively. As shown in the figure, the first surface 11 is the top surface of the main unit 1. The wet curtain duct chamber 13 is arranged around the atomizing chamber 12, such that the wet curtain air outlet 112 surrounds the spray nozzle 111. This surrounding arrangement includes either a diffuser 121 forming a complete annular shape around the spray nozzle 111, or a diffuser 121 forming an annular shape with a certain arc, such as a semicircle or a quarter circle, around the spray nozzle 111. The water pump assembly 5 supplies water from the water tank 2 into the wet curtain assembly 4 and the atomizing chamber 12. The atomizing assembly 3 generates mist in the atomizing chamber 12. The mist is blown out from the spray nozzle 111. Air passes through the wet curtain 41 and the wet curtain air duct chamber 13, and is blown out from the wet curtain air outlet 112. The mist and the humidified air that has passed through the wet curtain 41 are blown out separately. The two are relatively independent, so that the composite humidifier can be turned on with or without mist humidification, or it can be turned on with and without mist humidification at the same time. Furthermore, when both mist humidification and non-mist humidification functions are activated simultaneously, the relative positions of the wet curtain air duct cavity 13 and the wet curtain air outlet 112 to the atomizing cavity 12 and the spray nozzle 111 allow the air blown out of the wet curtain air outlet 112 to guide and diffuse the mist blown out of the spray nozzle 111, enabling the mist to diffuse faster and farther, thus preventing it from accumulating around the humidifier and causing excessive humidity.

[0028] like Figure 2 As shown, the evaporative cooling pad assembly 4 includes an evaporative cooling pad 41, and the water pump assembly 5 includes a water supply pump 51 and an overflow pipe 52. The inlet of the water supply pump 51 is connected to the water tank 2, and the outlet of the water supply pump 51 is connected to the atomizing chamber 12. The overflow pipe 52 connects the atomizing chamber 12 and the evaporative cooling pad 41. The water supply pump 51 injects water into the atomizing chamber 12, and the water level in the atomizing chamber 12 overflows the upper opening of the overflow pipe 52 and flows along the overflow pipe 52 to the evaporative cooling pad 41. By using the same water supply pump 51 to simultaneously inject water into the atomizing chamber 12 and the evaporative cooling pad 41, the structure of the composite humidifier becomes more compact. When the overflow pipe 52 injects water into the atomizing chamber 12, the water level in the atomizing chamber 12 can always be maintained at the same height as the upper opening of the overflow pipe 52.

[0029] like Figure 2 and Figure 4 As shown, the main unit 1 has an atomizing housing 14 and a wet curtain duct housing 15. The atomizing chamber 12 is formed in the atomizing housing 14. The wet curtain duct housing 15 is arranged around the atomizing housing 14. The wet curtain duct chamber 13 is formed between the atomizing housing 14 and the wet curtain duct housing 15. An extension 141 extending out of the wet curtain duct housing 15 is provided on one side of the atomizing housing 14. A water inlet 1411 is provided in the extension 141, which is connected to the outlet of the water supply pump 51. The atomizing housing 14 includes an atomizing water tank 142, an atomizing cover 143, and an atomizing cap 144. The extension 141 is provided on the side of the atomizing water tank 142 and is connected to the atomizing water tank 142, so that water injected through the water inlet 1411 can be injected normally. The water flows into the atomizing water tank 142. In addition, the upper end of the overflow pipe 52 is also provided in the extension 141, and the upper pipe opening of the overflow pipe 52 is higher than the extension 141 and the bottom surface of the atomizing water tank 142. The atomizing cover 143 is provided in the atomizing water tank 142, and the outer side wall of the atomizing cover 143 is opposite to the inner side wall of the atomizing water tank 142. The atomizing chamber 12 is formed between the atomizing cover 143 and the atomizing water tank 142. The spray nozzle 111 is provided on the atomizing cover 144. The atomizing cover 144 is located on the top surface of the main unit 1. A mist outlet pipe 1431 is formed on the atomizing cover 143. The mist outlet pipe 1431 is connected to the atomizing cover 144 and connects the mist outlet pipe 1431 with the spray nozzle 111, thereby connecting the atomizing chamber 12 with the spray nozzle 111.

[0030] like Figure 5As shown, the bottom surface of the atomizing water tank 142 is provided with a first mounting position 1423 and a second mounting position 1222. The atomizing component 3 also includes an atomizing plate 31 and a water level sensor 32. The atomizing plate 31 is fixed to the first mounting position 1423 by screws. The first mounting position 1423 has a perforation in the middle. The atomizing plate 31 contacts the water in the atomizing chamber 12 through the perforation, so that the atomizing plate 31 is used to atomize the water in the atomizing chamber 12 to produce mist.

[0031] like Figure 3 As shown, the water level sensor 32 includes a Hall effect device 321 and a float 322 with a magnet. The second mounting position 1222 forms a limiting member on the outer bottom surface of the atomizing water tank 142, with a mounting hole in the middle. A limiting post is formed inside the atomizing water tank 142 corresponding to the mounting hole. The Hall effect device 321 is mounted on the outside of the atomizing water tank 142. The lower end of the Hall effect device 321 is limited by the limiting member, and the upper end of the Hall effect device 321 extends into the mounting hole. The float 322 is located inside the atomizing water tank 142. The float 322 is installed on the side and is limited by the second mounting position 1222 in the atomizing chamber 12. It floats up and down with the water level in the atomizing chamber 12. The float 322 is specifically ring-shaped and is fitted on the limiting post, so that the float 322 can float up and down with the water level. A limiting cap 1224 is set on the top of the limiting post. The limiting cap 1224 further limits the float 322 to prevent the float 322 from falling out of the limiting post due to abnormal events such as excessive water level or tilting of the main unit 1.

[0032] like Figure 5 As shown, the evaporative cooling duct housing 15 is divided into an upper part 153 and a lower part 152. The upper part 153 is integrally formed with the atomizing water tank 142 and the extension 141. The upper part 153 surrounds the atomizing water tank 142 in a C-shape. The two ends of the upper part 153 are connected to the extension 141. The upper part 153 and the outer wall of the atomizing water tank 142 are connected by a reinforcing rod 154. The upper part 153 strengthens the overall structural strength of the atomizing water tank 142 and the extension 141, making the atomizing water tank 142 and the extension 141 less prone to deformation. After assembly, the upper part 153 and the lower part 152 will be joined together to form the evaporative cooling duct housing 15. The lower part 152 is also provided with a notch 151 for the extension 141 to extend out of the evaporative cooling duct housing 15.

[0033] like Figure 2 and Figure 5As shown, the atomizing housing 14 also includes a motor mounting base 145, which is located at the lower end of the atomizing water tank 142. The evaporative cooling pad assembly 4 also includes an evaporative cooling pad fan 42, which includes a motor 422 and a fan wheel 421. The motor 422 is fixed to the motor mounting base 145, and the output shaft 423 of the motor 422 passes through the motor mounting base 145 and extends into the evaporative cooling pad air duct cavity 13. The fan wheel 421 is fixed in the evaporative cooling pad air duct cavity 13. Specifically, on the output shaft 423, the motor mounting base 145 includes a mounting groove 1451 and a limiting plate 1452. The motor 422 is disposed in the mounting groove 1451. The limiting plate 1452 is fixed with screws to the screw fixing post on the inner side wall of the mounting groove 1451, so that the motor 422 is limited in the mounting groove 1451. The output shaft 423 of the motor 422 passes through the limiting plate 1452 and is connected to the impeller 421 for transmission. The impeller 421 is disposed in the wet curtain air duct cavity 13.

[0034] like Figures 1 to 2 , Figures 6 to 8 As shown, the second surface 16 of the main unit 1 forms a first air inlet 164, which is opposite to the air inlet end of the evaporative cooling pad fan 42. The evaporative cooling pad 41 is annular and is installed inside the water tank 2. The water tank 2 is provided with a bracket 22, and the evaporative cooling pad 41 is mounted on the bracket 22. The water tank 2 is provided with a second air inlet 21, which is opposite to the side of the evaporative cooling pad 41. The main unit 1 is detachably mounted on the water tank 2 via the second surface 16, so that the middle part of the evaporative cooling pad 41 is opposite to the first air inlet 164. As shown in the figure, the second surface 16 is the bottom surface of the main unit 1. An installation step 163 is formed on the outer side of the bottom surface. The main unit 1 is detachably installed on the water tank 2 through the installation step 163. The top surface of the water tank 2 abuts against the step surface of the installation step 163. When the wet curtain 41 humidifies, the wet curtain fan 42 is started. Air is drawn in through the second air inlet 21 and becomes humid air after passing through the wet curtain 41. The humid air is drawn into the wet curtain air duct cavity 13 through the first air inlet 164 and blown out from the wet curtain air outlet 112 along the wet curtain air duct cavity 13 under the push of the wet curtain fan 42.

[0035] like Figure 7 and Figure 8 As shown, the water pump assembly 5 also includes a water pump housing 511, which is fitted with the inner wall of the water tank 2 to form a water pump cavity. The water pump housing 511 can be fixedly connected to the inner wall of the water tank 2 by ultrasonic welding. The water supply pump 51 is installed in the water pump cavity. The water inlet end of the water supply pump 51 extends out of the water pump housing 511, and the water outlet end of the water supply pump 51 is connected upward to the water supply socket 512 formed on the top of the water pump housing 511. A power supply plug 513 is also formed on the top of the water pump housing 511.

[0036] like Figure 6 and Figure 7 As shown, the main unit 1 has a mounting surface that is detachably installed with the water tank 2. This mounting surface is also the second surface 16 of the main unit 1, i.e., the bottom surface of the main unit 1. A water supply plug 161 and a power supply socket 162 are formed on the mounting surface. The water supply plug 161 communicates with the atomizing chamber 12. The main unit 1 is installed on the water tank 2 such that the water supply plug 161 is plugged into the water supply socket 162 and the power supply plug 162 is plugged into the power supply socket 162. The main unit 1 is installed on the water tank 2. Above, the outlet end of the water supply pump 51 is connected to the water supply socket 512 through a pipe. The water supply socket 512 is plugged into and connected to the water supply plug 161. The water supply plug 161 is connected to the water inlet 1411 of the extension part 141 through a pipe. Water is injected into the water inlet 1411 by the water supply pump 51, so that the water flows naturally into the atomizing chamber 12. Through the electrical connection structure formed between the main unit 1 and the water tank 2, the main unit 1 can easily provide power and communication to the water supply pump 51.

[0037] like Figure 2 and Figure 6 As shown, the overflow pipe 52 is divided into two parts, including an overflow insertion tube 521 and a long tube body 522. The overflow insertion tube 521 is integrally formed with the extension part 141. The overflow insertion tube 521 extends into the extension part 141, so that the upper opening of the overflow pipe 52 is higher than the bottom surface of the extension part 141 and the atomizing water tank 142, forming an overflow effect. The overflow insertion tube 521 extends downward from the bottom surface of the outer side of the extension part 141 for the long tube body 522 to be inserted and installed. The long tube body 522 extends out from the perforation on the bottom surface of the main unit 1, so that the lower opening of the overflow pipe 52 is opposite to the wet curtain 41.

[0038] This application also provides embodiments of the fans for two types of composite humidifiers.

[0039] In this embodiment, both the evaporative cooling pad assembly 4 and the atomizing assembly 3 are equipped with fans. The evaporative cooling pad assembly 4 also includes an evaporative cooling pad fan 42, which is disposed in the evaporative cooling pad air duct cavity 13. The atomizing assembly 3 includes an atomizing fan 33. The evaporative cooling pad fan 42 guides air through the evaporative cooling pad 41 and blows it out from the evaporative cooling pad air outlet 112. The atomizing fan 33 blows air into the atomizing cavity 12, blowing the mist out from the spray nozzle 111. The evaporative cooling pad fan 42 uses a larger fan than the atomizing fan 33, so that the wind speed blown out from the evaporative cooling pad air outlet 112 is greater than the wind speed blown out from the spray nozzle 111. Thus, the high-speed airflow blown out from the evaporative cooling pad air outlet 112 can perform secondary humidification on the slow airflow blown out from the spray nozzle 111, thereby allowing the mist to be blown higher and the diffusion area to be larger.

[0040] like Figure 4 and Figure 5As shown, the atomizing fan 33 is installed on the bottom surface outside the atomizing water tank 142. The atomizing water tank 142 forms a blowing pipe 1421. The air outlet of the atomizing fan 33 is opposite to the blowing pipe 1421, and air is blown into the atomizing chamber 12 through the blowing pipe 1421.

[0041] like Figure 2 and Figure 5 As shown, in order to avoid affecting the air intake of the atomizing fan 33, a third air inlet 146 is provided at the bottom of the mounting groove 1451. There is a gap between the limiting plate 1452 and the outer wall of the mounting groove 1451, and there is also a gap between the impeller 421 and the limiting plate 1452. Through these gaps and the third air inlet 146, the atomizing fan 33 can take in air normally.

[0042] In this embodiment, only the wet curtain assembly 4 is equipped with a fan. The main unit 1 also includes a bypass ventilation duct. The wet curtain assembly 4 also includes a wet curtain fan 42. The wet curtain fan 42 is disposed in the wet curtain duct cavity 13. The wet curtain duct cavity 13 is connected to the atomizing cavity 12 through the bypass ventilation duct. The wet curtain fan 42 guides air through the wet curtain 41. Part of the air is blown out from the wet curtain air outlet 112, and another part of the air is blown into the atomizing cavity 12 through the bypass ventilation duct, thereby blowing the mist out from the spray nozzle 111. Preferably, the bypass ventilation duct is disposed on the motor 422 mounting housing on the rear side of the air outlet end of the wet curtain fan 42. From this point, the air blown out by the wet curtain fan 42 can be conveniently introduced into the atomizing cavity 12.

[0043] In addition, this application also provides an embodiment in which water is supplied to the wet curtain assembly 4 and the atomizing chamber 12 by two water pumps respectively. The water pump assembly 5 includes an atomizing water pump and a wet curtain water pump. The water supply pump and the overflow pipe are replaced by the atomizing water pump and the wet curtain water pump. The water inlet of the atomizing water pump is connected to the water tank, the water outlet of the atomizing water pump is connected to the atomizing chamber 12, the water inlet of the wet curtain water pump is connected to the water tank, and the water outlet of the wet curtain water pump is connected to the wet curtain assembly. Compared with the embodiment in this application that supplies water by one water pump, this embodiment supplies water by two water pumps, so that if one water pump fails, it will not affect the normal operation of the other assembly.

[0044] 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.
