Description

Technical Field

[0001] This application relates to the field of air treatment technology, and in particular to an air treatment device and a humidification device. Background Technology

[0002] In modern life, people are paying increasing attention to the air quality of their living environment. With the diversification of people's needs for air quality, humidifiers have become an important device for improving indoor air humidity and are widely used in homes. This function releases an appropriate amount of moisture into the air, regulating humidity and preventing excessively dry air from causing discomfort to the respiratory tract and skin, thus further optimizing the indoor air environment and providing users with a more comfortable experience.

[0003] However, existing humidification devices have some technical problems. One issue is that the water tank used for humidification often needs to be disassembled because it requires regular refilling or cleaning. However, in some products, leaks frequently occur in the water pipes connecting the water tank during and after disassembly, resulting in a poor user experience and, in some cases, damage to electrical components.

[0044] To make the technical solutions and beneficial effects of this application more obvious and understandable, the technical solutions in the embodiments of this application are clearly and completely described below by listing specific embodiments. Obviously, the embodiments of this application are not exhaustive, and the described embodiments are only some embodiments of this application, not all embodiments.

[0045] The exemplary embodiments disclosed in this application will now be described in more detail with reference to the accompanying drawings, providing detailed structures and steps to illustrate the technical solution of this application. Note that the drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0047] The following description provides numerous specific details to offer a more thorough understanding of this application. However, it will be apparent to those skilled in the art that this application can be practiced without one or more of these details. To clearly define the inventive concept of this application and avoid confusion with its content, technical features well-known in the art and conventionally understood by those skilled in the art are not described in detail. Specifically, this document does not fully list all features of actual embodiments, nor does it provide a detailed description of well-known functions and structures.

[0048] To address the technical problems in the prior art, embodiments of this application provide an air handling device. (Reference) Figures 1-5 The air handling equipment includes:

[0049] Housing 10, having a processing cavity;

[0050] The evaporative cooling pad assembly 20 is configured to increase the humidity of the air; the evaporative cooling pad assembly 20 is located in the processing chamber and has a first water channel.

[0051] A water pump assembly 30 is configured to supply water and / or recycle water to the evaporative cooling pad assembly 20; the water pump assembly 30 is detachably mounted to the housing 10; the water pump assembly 30 has a second water passage integrated into the first connector 32.

[0052] The second connector 40 is disposed on the housing 10 and has at least one or two connection channels for connecting the first connector 32 and the first water channel.

[0053] The valve stem 50 is disposed in at least one connection channel within the second connector 40 and is movable within the connection channel;

[0054] A reset member 60 is connected to the valve stem 50. When the water pump assembly 30 is installed on the housing 10, the valve stem 50 is squeezed and moves to a first position. After the water pump assembly 30 is detached from the housing 10, the valve stem 50 moves to a second position under the action of the reset member 60. When the valve stem 50 is in the first position, the first water passage and the second water passage are connected. When the valve stem 50 is in the second position, the passage between the first water passage and the second water passage is closed.

[0055] The first power-on connection terminal 33 and the second power-on connection terminal 34 are respectively disposed on both sides of the first connector 32. The first power-on connection terminal 33 and the second power-on connection terminal 34 are respectively the positive connection terminal and the negative connection terminal, and are connected to the water pump assembly 30 to realize the electrical connection of the water pump assembly 30.

[0056] Understandably, air handling equipment, such as humidifiers or air purifiers with humidification functions, needs to process the gas to generate humidified air before discharging it, in order to gradually purify / humidify the air.

[0057] Understandably, housing 10 includes not only the outer shell but also the support structure for mounting various components. For example, the second connector 40 may be disposed on housing 10, or it may be disposed on a support structure inside housing 10.

[0058] Understandably, the evaporative cooling pad assembly 20 requires timed or intermittent water intake, or continuous water intake, to humidify the air during or after treatment. Furthermore, water overflowing from the evaporative cooling pad assembly 20 needs to be drained promptly; therefore, a first water channel is provided. (Appendix) Figure 1 The solid arrows indicate the direction of water flow into the evaporative cooling pad assembly, while the dashed arrows indicate the direction of water flow overflowing from the evaporative cooling pad assembly. That is, the first water channel can have water inlet / outlet, or it may include at least one inlet channel and at least one outlet channel.

[0059] Specifically, the water pump assembly 30 can be located below the evaporative cooling pad assembly 20. This is beneficial for the stability of the air handling unit's center of gravity. Therefore, the water pump assembly 30 can include a water pump 37 and a water tank, and is provided with a second water passage to transport water from the water tank to the evaporative cooling pad assembly 20, and / or to collect water overflowing from the evaporative cooling pad assembly 20 back into the water tank. That is, the second water passage can be for water inlet / outlet, or it can include at least one water inlet passage and at least one water outlet passage.

[0060] Understandably, since the water pump assembly 30 requires periodic water replenishment or cleaning, it needs to be frequently disassembled from the housing 10 during use. Therefore, the first connector 32 and the second connector 40 are provided to allow the second water passage to connect with the first water passage during installation without the need for additional connections.

[0061] Understandably, the valve stem 50 and the reset element 60 function as a simple valve, eliminating the need for an additional valve and reducing costs. Furthermore, the valve stem 50 and the reset element 60 have a simple structure and are easy to install. It is understood that the movement of the valve stem 50 in two positions achieves the function of connecting or closing; many structures exist, and this embodiment does not specifically limit this; please refer to other embodiments for details.

[0062] It should be noted that the valve stem 50 and the reset piece 60 can be set in any one of the connection channels in the second connector 40, or they can be set in all the connection channels, depending on actual needs.

[0063] Understandably, the first power-contact terminal 33 and the second power-contact terminal 34, which are the positive and negative terminals electrically connected to the power supply of the air handling equipment, are separately provided. Compared with the prior art where the power-contact terminals are located on the same side, this reduces the possibility of short circuits caused by water leakage or seepage leading to continuity between the two power-contact terminals, thus improving the safety and stability of the air handling equipment. The term "power-contact terminal" is a collective term for the first power-contact terminal 33 and the second power-contact terminal 34. It is understood that any other power-contact terminals mentioned below can also be collectively referred to as "power-contact terminals."

[0064] In this embodiment, a valve stem and a reset component are provided within the second connector connecting the water pump assembly. After the water pump assembly is installed into the housing, the valve stem is squeezed to move to the first position, connecting the first water passage and the second water passage. After the water pump assembly is disassembled, the valve stem moves to the second position under the action of the reset component, closing the passage between the first and second water passages. This provides a good sealing effect and a simple structure. Furthermore, the first and second energized terminals for electrical connection of the water pump assembly are respectively located on both sides of the first connector, separating the positive and negative terminals. This reduces the possibility of short circuits caused by leakage or seepage, improving the electrical safety and stability of the air handling equipment.

[0065] In some embodiments of this application, the first water passage includes a first inlet pipe 21 and a first outlet pipe. The first inlet pipe 21 is configured to deliver water pumped from the pump assembly 30 to the evaporative cooling pad assembly 20. The first outlet pipe is configured to collect water overflowing from the evaporative cooling pad assembly 20 back into the pump assembly 30.

[0066] In some embodiments of this application, the second water passage includes a second outlet pipe 31 and a second inlet pipe. The second outlet pipe 31 is configured to deliver water pumped from the pump assembly 30 to the first water passage. The second inlet pipe is configured to collect water recovered from the first water passage into the pump assembly 30.

[0067] In some embodiments of this application, the connecting channel has a first stepped hole, and the valve stem 50 has a rod end 51 with a diameter larger than the small hole in the first stepped hole; when the valve stem 50 is in the second position, the rod end 51 and the first step surface 411 of the first stepped hole abut against each other, so that one end of the connecting channel connected to the second water outlet pipe 31 is closed; when the valve stem 50 is in the first position, the rod end 51 and the first step surface 411 are separated, and the first water inlet pipe 21 and the second water outlet pipe 31 are connected.

[0068] One end of the connecting channel that connects to the second water outlet pipe 31 is closed, thus sealing off the passage between the first water passage and the second water passage. The first water inlet pipe 21 and the second water outlet pipe 31 are connected, as are the first water passage and the second water passage.

[0069] The sealing effect is achieved through the contact between the end 51 of the valve stem and the first stepped surface 411. In principle, this is a mechanical planar seal, which offers advantages such as reliable sealing, long service life, easy maintenance, and low processing cost. It is understandable that a seal can be achieved without the first stepped hole; for example, by creating a hole in the side wall of the connecting channel. The valve stem 50 can close the seal when it moves to the opening position; otherwise, it will not close.

[0070] Specifically, the first stepped hole can be two adjacent cylindrical holes with different diameters, and a first stepped surface 411 is formed at the junction. The rod end 51 can be a section of cylinder with a diameter larger than the small hole in the first stepped hole, but smaller than the large hole in the first stepped hole. Here, "small hole" and "large hole" are relative terms within the first stepped hole, and their specific dimensions are not limited.

[0071] In some embodiments of this application, the first stepped hole includes a first inner hole near the second water outlet pipe 31 and a second inner hole connected to the first inner hole, the diameter of the second inner hole being larger than the diameter of the first inner hole; when the valve stem 50 is in the second position, the first end face of the stem end 51 facing the first inner hole abuts against the first stepped surface 411.

[0072] In terms of longitudinal section, the first stepped hole is shaped like a "T," with the larger end further away from the second outlet pipe 31. Therefore, the junction of the first inner hole and the second inner hole naturally forms a first stepped surface 411 facing the rod end 51. During movement, the valve stem 50 can close the connecting channel through the contact between the first end face and the first stepped surface 411. This is closer to the second outlet pipe 31 and also closer to the second water passage.

[0073] In some embodiments of this application, the valve stem 50 further includes a stem body 52 connected to the first end face, the diameter of the stem body 52 being less than or equal to the diameter of the first inner hole; when the water pump assembly 30 is installed to the housing 10, the stem body 52 of the valve stem 50 is squeezed and moves away from the second water outlet pipe 31.

[0074] The rod 52 is designed to apply pressure during the installation of the water pump assembly 30. This pressure causes the second outlet pipe 31 and its accessories of the water pump assembly 30 to move closer to the valve stem 50, and after contacting the rod 52, it continues to move, pushing the rod 52 away from the second outlet pipe 31. This opens the closed connection channel. Alternatively, the rod 52 can be omitted; for example, the valve stem 50 can be moved away from the second outlet pipe 31 and the second water passage by water pressure.

[0075] In some embodiments of this application, the rod body 52 has a third inner hole; when the valve rod 50 is in the first position, the third inner hole opens at one end toward the second water outlet pipe 31 and connects to the second water outlet pipe 31, and the side wall of the other end of the third inner hole opens so that water flows from the second water outlet pipe 31 into the connecting channel through the third inner hole.

[0076] refer to Figure 5 The water flow path is as follows: the second water outlet pipe 31 enters the third inner hole through the opening at one end of the third inner hole facing the second water outlet pipe 31, and then flows out through the side wall opening at the other end of the third inner hole, enters the connecting channel, and then enters the first water inlet pipe 21 through the connecting channel, and then enters the wet curtain assembly 20. Figure 5 The arrows indicate the direction of water flow. It points towards the second outlet pipe 31, and also towards the second water passage.

[0077] Specifically, the rod body 52 can be a cylinder, and the third inner hole can be a cylindrical hole with the same axis as the rod body 52.

[0078] Understandably, a third inner hole is provided, with its other end opening from the side wall. This allows water to flow from the inside of the stem 52 without having to go through the outside of the stem 52. The stem 52 and the connecting channel can be configured as a hole-shaft fit with very small clearance, making the movement of the valve stem 50 smoother and more reliable.

[0079] Specifically, the opening at the other end of the third hole can be set at a position close to the end of the rod 51, so that the first end face of the end of the rod 51 and the first step surface 411 are no longer in contact, and the connecting channel can be opened.

[0080] In some embodiments of this application, a sealing ring 70 is provided at the contact point between the rod end 51 and the first stepped surface 411.

[0081] This can further improve the sealing performance. Understandably, since the diameters of the rod end 51 and the rod body 52 are not the same, a step is formed at the junction of the rod end 51 and the rod body 52, and the sealing ring 70 can be fitted onto the step.

[0082] Specifically, the sealing ring 70 can be an O-ring made of rubber.

[0083] Furthermore, an annular groove can be machined at the step to facilitate the axial fixation of the sealing ring 70. Specifically, the depth of the annular groove is less than half the wall thickness of the sealing ring 70 so as not to hinder the seal.

[0084] In some embodiments of this application, the water pump assembly 30 further includes a connecting pipe 80, one end of which is sleeved on the second water outlet pipe 31, and the other end is detachably sleeved on the connecting channel.

[0085] This facilitates the connection between the second outlet pipe 31 and the connecting channel when the water pump assembly 30 is installed onto the housing 10, and prevents leakage. It is fitted onto the second outlet pipe 31, and also fitted onto the second water passage.

[0086] Specifically, the connecting tube 80 can be made of silicone. Silicone has good elasticity, making installation more secure and easy to disassemble. It also has good wear resistance, allowing for repeated disassembly.

[0087] In some embodiments of this application, the connecting pipe 80 is fitted onto the inner wall of the connecting channel and is provided with a raised rib 81 to increase the connection strength.

[0088] The raised rib 81 increases friction and strengthens the connection between the connecting pipe 80 and the connecting channel. Specifically, the raised rib 81 can be an annular raised rib.

[0089] In some embodiments of this application, the connecting pipe 80 has a second stepped hole, the second stepped hole including a fourth inner hole sleeved on the second water outlet pipe 31 and a fifth inner hole sleeved on the connecting channel; the diameter of the fourth inner hole is smaller than the diameter of the fifth inner hole, and the second stepped surface 82 at the junction of the fourth inner hole and the fifth inner hole abuts against the end face of the rod body 52.

[0090] The connecting pipe 80 has fitting holes of different diameters at both ends to match the second outlet pipe 31 and the connecting channel, making the connection more secure and easy to disassemble. Furthermore, a second stepped surface 82 is formed at the junction of the fourth and fifth inner holes. This second stepped surface 82 allows the valve stem 50 to be squeezed when the pump assembly 30 is installed onto the housing 10, thus opening the connecting channel. The aforementioned rib 81 is located on the wall of the fifth inner hole. It is fitted onto the second outlet pipe 31 and also onto the second water passage.

[0091] In some embodiments of this application, the connection channel includes a first tube 412 and a second tube 413, the second tube 413 being sleeved on one end of the first tube 412; the inner cavity of the first tube 412 forms the first inner hole, and the inner cavity of the second tube 413 forms the second inner hole; the end face of the first tube 412 facing the second tube 413 forms the first stepped surface 411.

[0092] The connection channel in the second connector 40 is assembled by manufacturing the first tube 412 and the second tube 413 separately. This reduces manufacturing difficulty and maintenance costs.

[0093] In some embodiments of this application, the reset member 60 is a compression spring; one end of the compression spring abuts against the valve stem 50, and the other end abuts against the connecting channel.

[0094] The valve stem 50, which is abutted by the compression spring, is at the end furthest from the second water outlet, and the connecting channel is also at the end furthest from the second water outlet.

[0095] Compression springs are a common type of reset element 60. By adjusting the elastic modulus of the material, wire diameter, and number of coils, the elasticity can be controlled more precisely, and the cost is low. It is understandable that the reset element 60 can also be other elastic elements, such as gas springs. It can also be other structures, such as tension springs (the other hook of the tension spring needs to be hooked into the connection channel near the second water outlet). Additionally, automated components, such as hydraulic pumps, can be used.

[0096] Specifically, a step is provided at the end of the rod 51 facing the compression spring to facilitate the installation of the compression spring.

[0097] In some embodiments of this application, the water pump assembly 30 includes a water tank, which includes a tank body 35 and a tank cover 36; the first connector 32 is disposed on the tank cover 36; and the other ends of the second inlet pipe and the second outlet pipe 31 extend into the tank body 35.

[0098] The other end of the second inlet pipe and the second outlet pipe 31 is the same as the other end of the second water passage.

[0099] The first connector 32 is disposed on the cover 36, which facilitates the connection of the first connector 32 and the second connector 40 when the water pump assembly 30 is installed into the housing 10, and also facilitates maintenance.

[0100] refer to Figure 6 The water pump assembly 30 can be detached from one side of the housing 10. In this way, the disassembly and installation process does not affect the wet curtain assembly 20 located on the upper part of the housing 10.

[0101] refer to Figure 3 and Figure 7 The connection channel of the second connector 40, which mates with the first connector 32, may include a first connection channel 41 and a second connection channel 42. The first connection channel 41 is configured to connect the first water inlet pipe 21 and the second water outlet pipe 31. The second connection channel 42 is configured to connect the first water outlet pipe and the second water inlet pipe.

[0102] Specifically, the first connector 32 also includes a ventilation channel 43, configured to ventilate when water enters or exits the housing 35, which facilitates smooth water inflow or outflow.

[0103] It should be noted that the appendix Figure 3 and attached Figure 7 As can be seen, the first connecting channel 41 connects to the first water inlet pipe 21, and the second connecting channel 42 connects to the first water outlet pipe. The outward-facing ends of the second water inlet pipe and the second water outlet pipe 31 are integrated into the first connector 32 and mate with the second connector 40; therefore, they are covered by the connector housing and cannot be seen. (See also...) Figure 4 or Figure 5 See attached images. (For reference) Figure 8 and Figure 9 After the pump assembly 30 can be removed from the housing 10, the valve stem 50 moves towards the second outlet pipe 31 (moving to the left in the figure) under the action of the reset member 60, thus completing the closure of the connecting pipe 80.

[0104] In some embodiments of this application, reference is made to Figure 10 and Figure 11 The cover 36 is provided with an isolation chamber 3611, and the wire portions of the first power-connecting terminal 33 and the second power-connecting terminal 34 are both located in the isolation chamber 3611.

[0105] This better protects the wire portions of the first power-on connection terminal 33 and the second power-on connection terminal 34.

[0106] Specifically, electrical connection terminals for electrical components such as the water pump 37 are also installed inside the isolation chamber 3611. This allows the electrical connection terminals to establish electrical connections with the first energized connection terminal 33 and the second energized connection terminal 34 within the isolation chamber 3611. This ensures that the electrical connection portion of the water pump assembly 30 is not affected by the water in the tank 35.

[0107] Specifically, for ease of water change or maintenance, the water pump 37 of the water pump assembly 30 can also be fixed to the bottom of the tank cover 36. When removing the tank cover 36, the water pump 37 can also be removed at the same time. This also ensures that the electrical connection terminals of the water pump 37 are not affected during the removal of the tank cover 36.

[0108] Specifically, the cover 36 includes a cover body 361 and a sealing cover 362. The cover body 361 is provided with an isolation chamber 3611 with an opening at the top, and the sealing cover 362 is configured to close the isolation chamber 3611.

[0109] In some embodiments of this application, the air handling equipment further includes a third power-on connection terminal and a fourth power-on connection terminal disposed on the housing 10, respectively disposed on both sides of the second connector 40; when the water pump assembly 30 is installed to the housing 10, the first power-on connection terminal 33 and the third power-on connection terminal are electrically connected, and the third power-on connection terminal is electrically connected to the positive terminal of the power supply; the second power-on connection terminal 34 and the fourth power-on connection terminal are electrically connected, and the fourth power-on connection terminal is electrically connected to the negative terminal of the power supply.

[0110] In this way, the pump assembly 30 can be powered on after being installed in the housing 10 and powered off after being removed, via the power connection terminal.

[0111] The third and fourth power connection terminals, which are respectively located on both sides of the second connector 40, along with the first power connection terminal 33 and the second power connection terminal 34, can also reduce the possibility of short circuits caused by water leakage or seepage leading to conduction between the two power connection terminals, thereby improving the safety and stability of the air handling equipment.

[0112] This application also provides a humidification device, including the air handling device described above.

[0113] The humidification device of this embodiment includes a valve stem 50 and a reset member 60 within the second connector 40 connecting the water pump assembly 30. After the water pump assembly 30 is installed into the housing 10, the valve stem 50 is pressed to move, thus connecting the connection channel between the water pump assembly 30 and the evaporative cooling pad assembly 20. After the water pump assembly 30 is disassembled, the valve stem 50 closes the connection channel under the action of the reset member 60. This provides a good sealing effect and has a simple structure.
