Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and particularly to a humidifier. Background Art

[0002] Currently, for humidifiers using wet curtains, generally the wet curtain is immersed in a water tank, the wet curtain adsorbs water, and an electric fan blade is arranged at the top of the wet curtain. The air is blown out by driving of the fan blade, so as to use the air flow to take away the water on the wet curtain to achieve the purpose of humidification. In the process of humidifying the wet curtain, there is a problem that the wet curtain cannot be fully humidified, thus affecting the use effect of the humidifier. Summary of the Utility Model

[0003] Aiming at the problem that the wet curtain of the existing humidifier is not fully humidified during use, the present application provides a humidifier, which has the technical effect of being able to fully humidify the wet curtain.

[0004] A humidifier includes a housing and at least two spraying devices. An annular wet curtain is arranged inside the housing, and the annular wet curtain extends along a first direction; at least two spraying devices are located inside the housing, each spraying device includes an annular spraying head, and all the annular spraying heads are located inside the annular wet curtain; wherein, all the annular spraying heads are arranged along the first direction, and the annular spraying heads corresponding to adjacent two spraying devices do not overlap at least partially along the first direction; along the circumferential direction of the annular wet curtain, the spraying surface formed by all the annular spraying heads jointly covers the annular wet curtain.

[0005] Therefore, when the spraying device operates, the water flows sprayed by the annular spraying heads of the two spraying devices can spray different parts of the annular wet curtain and all cover the annular wet curtain, so as to humidify the annular wet curtain in all directions.

[0006] In one embodiment, the annular spraying head includes a body and a plurality of spraying groups. The plurality of spraying groups are arranged on the body and are spaced apart along the first direction. Each spraying group includes a plurality of spraying parts, and all the spraying parts of each spraying group form an annular shape around the axis of the annular wet curtain and are spaced apart on the body.

[0007] In this way, because spraying parts are arranged on the wall body of the body along the first direction and on the circumferential direction of the body, water can be discharged evenly within the spraying range of the spraying head to spray the wet curtain evenly.

[0008] In one embodiment, adjacent two spraying parts in each spraying group are equally spaced, and each spraying group is equally spaced along the first direction.

[0009] In this way, the annular spray head can discharge water evenly in the first direction and can also discharge water evenly without dead angles in its circumferential direction. When spraying the wet curtain, the wet curtain can be quickly and evenly wetted.

[0010] In one embodiment, the spray parts in two adjacent spray groups are arranged staggeredly along the first direction.

[0011] With such an arrangement, dead-angle spraying can be achieved in the circumferential direction of the main body, reducing the probability that some parts of the wet curtain are omitted and not within the spraying range of the annular spray head.

[0012] In one embodiment, each spray device further includes a water guide pipe. One end of the water guide pipe is connected to the annular spray head, and the other end is connected to a water pump. The water pump is arranged at the bottom of the housing, and the lengths of the water guide pipes corresponding to two adjacent spray parts are different.

[0013] In this way, the structure of the spray device is divided into multiple parts. By limiting the length of the water guide pipe, the installation height of the annular spray head can be limited, simplifying the structure of the spray device and facilitating the installation of the spray device.

[0014] In one embodiment, the water guide pipe is detachably connected to the annular spray head.

[0015] With such an arrangement, when any one of the water guide pipe and the annular spray head is damaged, the damaged one can be replaced with a new part. Compared with replacing the entire spray device, the maintenance cost of the spray device is reduced. In addition, different lengths of water guide pipes can be replaced according to the position of the annular wet curtain in the housing, so that the installation height of the annular spray head meets the requirements, and the corresponding water guide pipes can be replaced according to the installation position of the annular wet curtain in the housing, so that the spray heads of different spray devices can spray the corresponding parts of the annular wet curtain.

[0016] In one embodiment, the water guide pipe is telescopically arranged along the first direction.

[0017] With such an arrangement, the flexibility of the water guide pipe is improved, the application range of the spray device is broadened, and it can be applied to humidifiers of various sizes.

[0018] In one embodiment, the water pumps correspond to the water guide pipes one by one, and the water guide pipes are detachably connected to the water pumps.

[0019] With such an arrangement, when any one of the water pump and the water guide pipe is damaged, only the damaged one needs to be replaced with a new part. Compared with replacing the water pump and the water guide pipe together, the maintenance cost is reduced.

[0020] In one of the embodiments, the housing further includes a water tank, and the water pump is detachably disposed in the water tank.

[0021] Such an arrangement makes it easy for the user to install and disassemble the water pump, thereby cleaning the water pump, or when either the water pump or the water tank is damaged, the damaged parts can be replaced to reduce maintenance costs.

[0022] In one of the embodiments, a plurality of slots are provided at the bottom of the water tank, and the slots correspond to the water pumps one by one and are engaged with the water pumps.

[0023] Such an arrangement simplifies the installation method of the water pump, facilitates the installation and disassembly of the water pump, reduces the difficulty of installing the water pump, and speeds up the installation speed of the water pump. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Please refer to Figure 1 , in an embodiment of the present application, a humidifier 100 is provided, which includes a housing 10 and at least two spraying devices 20. An annular wet curtain 11 is provided inside the housing 10, and the annular wet curtain 11 extends along a first direction X; at least two spraying devices 20 are located inside the housing 10, and each spraying device 20 includes an annular spray head 21, and all the annular spray heads 21 are located inside the annular wet curtain 11. Among them, the annular spray heads 21 corresponding to each spraying device 20 are arranged along the first direction X, and the annular spray heads 21 corresponding to two adjacent spraying devices 20 do not overlap at least partially along the first direction X. Along the circumferential direction of the annular wet curtain 11, the spraying surface formed by all the annular spray heads 21 together covers the annular wet curtain 11.

[0036] Water can be contained in the housing 10, and the spraying device 20 can suck water and spray the sucked water onto the wet curtain through the annular spray head 21 to wet the wet curtain. The structures of the spraying devices 20 are similar and spray different parts of the wet curtain. The number of the spraying devices 20 can be two, three or more than three. All the spraying devices 20 can be arranged at intervals. After all the spraying devices 20 are installed in the housing 10, all the annular spray heads 21 are arranged along the first direction X. That is, the distances between each annular spray head 21 and the bottom of the housing 10 are different. When the humidifier 100 is in use, the first direction X is usually the vertical direction, so the heights of each annular spray head 21 are different.

[0037] It should be noted that in some examples, along the first direction X, some parts where different annular spray heads 21 are close to each other are at the same height. In this way, there are some water flows sprayed by different annular spray heads 21 that cover the same part of the annular wet curtain 11.

[0038] Exemplarily, as Figure 1 shown, the shape of the housing 10 can be generally cylindrical and extends along the first direction X. Two spraying devices 20 are provided inside the housing 10, and the annular spray heads 21 corresponding to the two spraying devices 20 are both located inside the annular wet curtain 11, and the annular spray heads 21 of each spraying device 20 can be distributed along the first direction X. That is, the heights of the annular spray heads 21 corresponding to the two spraying devices 20 are different. Coupled with the fact that the area sprayed by a single annular spray head 21 can cover the circumferential direction of the annular wet curtain 11.

[0039] Therefore, when the spraying device 20 operates, the water flows sprayed by the annular spray heads 21 of the two spraying devices 20 can spray different parts of the annular wet curtain 11 and completely cover the annular wet curtain 11, thereby humidifying the annular wet curtain 11 in all directions.

[0040] As Figure 2 shown, in some embodiments, the annular spray head 21 includes a body 211 and a plurality of spray groups. Each spray group includes a plurality of spray parts 212. The plurality of spray groups are arranged on the body 211 and are spaced apart along the first direction X. All the spray parts 212 of each spray group form an annulus around the axis of the annular wet curtain 11 and are spaced apart on the body 211.

[0041] The shape of the body 211 can be but is not limited to being cylindrical. Through holes are formed in the circumferential wall of the annular spray head 21, and the through holes are configured as the spray parts 212. A plurality of spray parts 212 distributed along the first direction X can be divided into one spray group, and each spray group is composed of a plurality of spray parts 212 forming an annulus.

[0042] Because the wall of the body 211 along the first direction X and the circumference of the body 211 are both provided with the spray parts 212, within the spraying range of the spray head, water can be discharged evenly to spray the wet curtain evenly.

[0043] Specifically, please refer to Figure 2 , in some embodiments, adjacent two spray parts 212 in each spray group are equally spaced, and each spray group is equally spaced along the first direction X.

[0044] Exemplarily, along the first direction X, the body 211 is provided with ten spray groups, and the interval between adjacent two spray groups is 10 mm. Each spray group includes 10 spray parts 212, that is, the body 211 is provided with a spray part 212 every 36° along its circumference.

[0045] In this way, the annular spray head 21 can discharge water evenly in the first direction X and can also discharge water evenly and without dead angles in its circumference. When spraying the wet curtain, the wet curtain can be quickly and evenly wetted.

[0046] More specifically, in some embodiments, the spray parts 212 in adjacent two spray groups are staggered along the first direction X.

[0047] In other words, the plurality of spray parts 212 arranged on the body 211 along the first direction X are not on the same straight line. In this way, dead-angle-free spraying can be achieved in the circumference of the body 211, and the probability that some parts of the wet curtain are missed and not within the spraying range of the annular spray head 21 can be reduced.

[0048] Certainly, in some embodiments, along the first direction X, the corresponding injection parts 212 in two adjacent injection groups are distributed along the same straight line. As Figure 2 shown, the injection parts 212 on the side wall of the main body 211 are arranged in an array. In this way, the difficulty of opening the injection parts 212 in the main body 211 is reduced, and the speed of setting the injection parts 212 is increased.

[0049] In some embodiments, each injection device 20 further includes a water guide pipe 22. One end of the water guide pipe 22 is connected to the annular injection head 21, and the other end is connected to a water pump 23. The water pump 23 is arranged at the bottom of the housing 10, and the lengths of the water guide pipes 22 corresponding to two adjacent injection parts 212 are different.

[0050] In the embodiments of the present application, a submersible pump 23 can be used as the water pump 23. After the injection device 20 is assembled to the housing 10, because the lengths of the water guide pipes 22 corresponding to each injection device 20 are different, and the end of the water guide pipe 22 far from the water pump 23 is provided with an annular injection head 21, the installation heights of different annular injection heads 21 are different. When the injection device 20 operates, different water pumps 23 pump water, and the water is conveyed to the corresponding annular injection head 21 through the water guide pipe 22, and then sprayed to the wet curtain through the corresponding injection parts 212.

[0051] In this way, the structure of the injection device 20 is divided into multiple parts. By limiting the length of the water guide pipe 22, the installation height of the annular injection head 21 can be limited, the structure of the injection device 20 is simplified, and it is convenient to install the injection device 20.

[0052] Further, in some embodiments, the water guide pipe 22 and the annular injection head 21 are detachably connected. The connection manner between the water guide pipe 22 and the annular injection head 21 can be but is not limited to snap connection and threaded connection.

[0053] Exemplarily, as Figure 2 shown, the end of the water guide pipe 22 close to the annular injection head 21 is provided with a threaded connection portion, and a threaded hole is also opened on the annular injection head 21. The threaded hole is threadedly connected to the threaded connection portion to connect the annular injection head 21 and the water guide pipe 22 together.

[0054] When any one of the water guide pipe 22 and the annular injection head 21 is damaged, the damaged one can be replaced with a new component. Compared with replacing the entire injection device 20, the maintenance cost of the injection device 20 is reduced. In addition, different lengths of the water guide pipe 22 can be replaced according to the position of the annular wet curtain 11 in the housing 10, so that the installation height of the annular injection head 21 meets the requirements, and the corresponding water guide pipe 22 can be replaced according to the installation position of the annular wet curtain 11 in the housing 10, so that the injection heads of different injection devices 20 can spray the corresponding parts of the annular wet curtain 11.

[0055] In some embodiments, the water conduit 22 is telescopically disposed along the first direction X.

[0056] For example, the water conduit 22 includes a plurality of water conduit sections, and the connection between two adjacent water conduit sections may be, but is not limited to, sleeved or clamped. The user may adjust the overall length of the water conduit 22 according to the position of the annular wet curtain 11, so that the annular spray head 21 installed at the end of the water conduit 22 can be located inside the annular wet curtain 11 and spray all the water onto the surface of the annular wet curtain 11.

[0057] Such an arrangement improves the use flexibility of the water conduit 22 , broadens the use scope of the spray device 20 , and can be applicable to humidifiers 100 of various sizes.

[0058] Furthermore, if Figure 2 As shown, in some embodiments, the water pump 23 corresponds to the water pipe 22 one by one, and the water pipe 22 and the water pump 23 are detachably connected.

[0059] In other words, the number of water pumps 23 is equal to the number of water pipes 22, that is, one water pipe 22 is equipped with one water pump 23. Each water pump 23 includes a water inlet and a water outlet, and one end of the water pipe 22 is connected to the water outlet of the water pump 23, and the connection between the two can be but not limited to a clamping connection or a threaded connection.

[0060] When the water pump 23 is running, water is pumped through the water inlet, and the pumped water flows into the water pipe 22 through the water outlet, and then sprayed to the annular wet curtain 11 through the annular spray head 21. When either the water pump 23 or the water pipe 22 is damaged, the damaged one can be replaced with a new one, which reduces the maintenance cost compared to replacing the water pump 23 and the water pipe 22 together.

[0061] See also Figure 3 In some embodiments, the housing 10 further includes a water tank 12, and the water pump 23 is detachably disposed in the water tank 12. The water tank 12 is located at the bottom of the housing 10, and the water tank 12 and the housing 10 can be prepared by an integrated molding process. Alternatively, the water tank 12 is detachably installed in the housing 10, so that the user can take out the water tank 12 and clean it.

[0062] The water pump 23 is installed in the water tank 12. The connection between the water pump 23 and the water tank 12 can be, but is not limited to, bonding, clamping, or other methods that are easy to disassemble. This arrangement makes it easy for users to install and disassemble the water pump 23, so as to clean the water pump 23, or when either the water pump 23 or the water tank 12 is damaged, the damaged parts can be replaced to reduce maintenance costs.

[0063] Please continue reading Figure 3, in some embodiments, a plurality of clamping grooves 121 are provided at the bottom of the water tank 12. The clamping grooves 121 correspond to the water pumps 23 one by one and are clamped with the water pumps 23.

[0064] That is, the number of the clamping grooves 121 is equal to the number of the water pumps 23, and one water pump 23 is installed in one clamping groove 121.

[0065] With such a setting, the installation method of the water pump 23 is simplified, facilitating the installation and disassembly of the water pump 23, reducing the installation difficulty of the water pump 23, and accelerating the installation speed of the water pump 23.

[0066] In other embodiments, a mounting seat is provided at the bottom of the water tank 12, and the water pump 23 is mounted on the mounting seat. By providing a dedicated structure for mounting the water pump 23, the installation accuracy of the water pump 23 can be improved, and the spraying effect of the corresponding annular spraying head 21 caused by the deviation of the installation position of the water pump 23 from the preset position can be reduced.

[0067] As Figure 1 shown, in a specific embodiment, two spraying devices 20 are provided in the housing 10 of the humidifier 100. Each spraying device 20 includes a water pump 23, an annular spraying head 21 and a water guide pipe 22, and the lengths of the two water guide pipes 22 are not equal. A water tank 12 is provided at the bottom of the housing 10, and two clamping grooves 121 are provided on the bottom wall of the water tank 12. Each clamping groove 121 clamps a water pump 23. One end of the water guide pipe 22 is connected to the water pump 23, and the other end is provided with a threaded portion. The threaded portion is threadedly connected to the annular spraying head 21. Each water pump 23 is provided with a water inlet and a water outlet, the water outlet is communicated with the water guide pipe 22, and the water inlet communicates the water pump 23 with the water tank 12.

[0068] Since the lengths of the two water guide pipes 22 are not equal, the heights at which the two annular spraying heads 21 are installed in the housing 10 are also different. However, the two annular spraying heads 21 are both located within the annular wet curtain 11, and the spraying portions 212 of each annular spraying head 21 face different parts of the annular wet curtain 11.

[0069] When the spraying device 20 operates, the water pump 23 sucks the water in the water tank 12 from the water inlet, the sucked water flows through the water outlet to the water guide pipe 22, then to the annular spraying head 21, and is sprayed from different spraying portions 212 of the annular spraying head 21 to different parts of the annular wet curtain 11 to wet the wet curtain.

[0070] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0071] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
