Description

Technical Field

[0001] This utility model relates to the technical field of humidifiers, and in particular to a waterproof electrical connection structure for a water tank. Background Technology

[0002] In the prior art, the lower water tank of the humidifier is equipped with electronic devices such as a water pump, solenoid valve, and liquid level sensor to realize automatic water replenishment and automatic water filling of the water tank. Therefore, when the lower water tank is connected to the main water circuit structure of the humidifier, it also needs to be electrically connected to the control circuit of the humidifier.

[0003] The common electrical connection method is to connect the water tank and the humidifier body through a waterproof electrical plug. This mainly relies on the waterproof electrical connection between the male and female connectors. The male and female connectors need to fit tightly to ensure waterproofing, but this tight fit can also make it inconvenient for users to remove the water tank.

[0004] In addition to the aforementioned pluggable connectors, there is also a spring pin connector, which is a commonly used electrical connector in home appliances. It mainly uses spring pins to achieve flexible electrical connection between electronic devices and other electronic devices and circuit boards. Compared with pluggable connectors, spring pin connectors can form an electrical connection as long as they make contact, making them more suitable for electrical connections between two separately designed components.

[0005] However, spring pin connectors also have disadvantages. Spring pin connectors have multiple spring pins, which are closely spaced together. When wet, water can easily clump together between adjacent spring pins, causing a short circuit between them and affecting the electrical safety of the equipment. Summary of the Invention

[0006] The main purpose of this utility model is to provide a waterproof electrical connection structure for water tanks, which can reduce the risk of short circuits when spring pin connectors are used as electrical connectors in water tanks.

[0007] To achieve the above objectives, the water tank's waterproof electrical connection structure includes: A cover plate is installed on the water tank. The cover plate is equipped with a spring pin connector that connects to electronic components inside the water tank. The elastic end of the spring pin connector protrudes from the cover plate. The surface of the cover plate is provided with a water-blocking strip that separates the elastic ends of two adjacent spring pin connectors.

[0008] Compared with existing technologies, the water tank waterproof electrical connection structure provided by this utility model involves placing a spring pin connector on a cover plate, with the elastic end of the spring pin connector protruding from the surface of the cover plate. A water-blocking strip is provided on the surface of the cover plate to separate the elastic ends of two adjacent spring pin connectors. In this way, when the cover plate gets wet, the water-blocking strip can separate the spring pin connectors, reducing the possibility of water adhering to the elastic ends of adjacent spring pin connectors spreading and accumulating together along the surface of the cover plate, thereby reducing the risk of short circuits in the spring pin connectors.

[0009] In some alternative embodiments, the cover plate has a contact area, the resilient end of the spring pin connector is located within the contact area, and both ends of the water-blocking strip extend to the edge of the contact area.

[0010] In this way, the contact area of ​​the spring pin connector is divided into small, non-connected regions, further preventing the elastic ends of two adjacent spring pin connectors from short-circuiting due to water contact.

[0011] In some alternative embodiments, the outer wall of the water tank is provided with a receiving groove, the cover plate is disposed in the receiving groove, and the end face of the groove wall protrudes from the plane where the end face of the water baffle is located.

[0012] This is to prevent the end face of the water-blocking strip from sliding into contact with the humidifier housing / base and causing wear.

[0013] In some alternative embodiments, the spring pin connector includes a pin seat, a spring pin disposed on the pin seat, and a first sealing ring sleeved on the pin seat; a mounting groove is provided on the back of the cover plate, and a clearance hole is provided at the bottom of the mounting groove for the elastic end of the spring pin to pass through; the pin seat is engaged in the mounting groove, and the first sealing ring is pressed tightly in the mounting groove by the seat body portion of the pin seat.

[0014] This ensures waterproofing between the spring pin connector and the cover plate, preventing water from outside the cover plate from entering the cover plate through the spring pin connector.

[0015] In some alternative embodiments, a protruding ring is provided in the mounting groove, and the clearance hole is located inside the protruding ring.

[0016] This increases the deformation of the first sealing ring, thus improving the sealing performance.

[0017] In some alternative embodiments, a peripheral wall is provided around the outer periphery of the cover plate, and a groove is recessed on the end face of the peripheral wall that contacts the water tank, and a second sealing ring is provided in the groove.

[0018] This ensures a tight seal between the cover and the water tank.

[0019] In some alternative embodiments, screw holes are provided on the outer side of the peripheral wall, and the cover plate is locked onto the water tank by screws passing through the screw holes.

[0020] In this way, the cover plate is effectively fixed, ensuring that the second sealing ring is compressed to achieve an effective seal.

[0021] In some alternative embodiments, the cover plate is disposed on the outer wall of the bottom of the water tank.

[0022] This is to reduce the impact of the cover on the appearance of the water tank.

[0023] In some alternative embodiments, the water tank waterproof electrical connection structure further includes a conductive seat disposed on the base supporting the water tank, the conductive seat corresponding to the spring pin connector, and the contact end of the conductive seat protruding from the support surface of the base.

[0024] This ensures that the spring pin connector and the conductive base can form an effective electrical contact.

[0025] In some alternative embodiments, the water tank waterproof electrical connection structure also includes a wireless power supply module disposed on a base supporting the water tank.

[0026] In this way, power is supplied to some wireless electronic devices in the water tank. Attached Figure Description

Detailed Implementation

[0035] The waterproof electrical connection structure of the water tank according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] The water tank waterproof electrical connection structure provided by this utility model can be applied to the water tank of a humidifier. It includes a cover plate set on the water tank and a spring pin connector set on the back of the cover plate. The elastic end of the spring pin connector extends from the back of the cover plate to the surface of the cover plate. The surface of the cover plate is provided with a water-blocking strip that separates the elastic ends of two adjacent spring pin connectors.

[0037] In this way, when the cover plate gets wet, the water-blocking strip can separate the adjacent spring pin connectors, reducing the possibility that the water adhering to the elastic end of the adjacent spring pin connectors will spread along the surface of the cover plate and clump together, thereby reducing the risk of short circuit of the spring pin connectors.

[0038] For example, refer to Figure 2 and Figure 6 In this embodiment, a first cover plate 30 is provided at the bottom of the water tank 10, and four spring pin connectors 40 are provided on the back of the first cover plate 30. The four spring pin connectors 40 are connected to the solenoid valve and TDS sensor inside the water tank 10. The elastic ends of the four spring pin connectors 40 protrude from the first cover plate 30 and protrude from the surface of the first cover plate 30. The four spring pin connectors 40 are generally distributed along the width direction of the first cover plate 30 and staggered along the length direction of the first cover plate 30 so that adjacent spring pin connectors 40 maintain a certain distance. Water-blocking strips 31 are respectively provided at the intervals between each pair of the four spring pin connectors 40 along the length direction of the first cover plate 30, so that two adjacent spring pin connectors 40 are separated in the width direction of the first cover plate 30.

[0039] In this way, when the spring pin contact area of ​​the first cover plate 30 gets wet, these water-blocking strips 31 can prevent the water adhering to the elastic end of the spring pin connector 40 from accumulating along the surface of the first cover plate 30, thereby connecting the adjacent spring pin connectors 40.

[0040] It is understandable that the same effect can be achieved when the first cover plate 30 is located on the periphery or top of the water tank 10.

[0041] In some alternative embodiments, the outer surface of the cover plate is provided with a contact area, the elastic end of the spring pin connector is located within the contact area, and the two ends of the water-blocking strip extend to the edge of the contact area.

[0042] For example, refer to Figure 2 In this embodiment, a rectangular contact area 30a is provided on the surface of the first cover plate 30. The edge of the rectangular contact area 30a maintains a certain distance from the spring pin connector 40. The water-blocking strip 31 between two adjacent spring pin connectors 40 is provided along the length direction of the first cover plate 30. Both ends of each water-blocking strip 31 extend to the edge of the rectangular contact area 30a.

[0043] In this way, the water-blocking strip 31 divides the rectangular contact area 30a into four relatively independent small areas. When the elastic end of the spring pin connector 40 gets wet, it can prevent the water attached to the elastic end from spreading to the adjacent area.

[0044] In some optional embodiments, a receiving groove is provided on the outer wall of the water tank, and a cover plate is provided in the receiving groove, with the end face of the groove wall protruding from the plane where the end face of the water baffle is located.

[0045] For example, refer to Figure 1 and 4 A first circumferential wall 11 is provided around the bottom edge of the water tank 10, thereby forming a receiving groove 10a at the bottom of the water tank. The first cover plate 30 is placed in the receiving groove 10a, and the end face of the first circumferential wall 11 protrudes from the plane where the end face of the water baffle is located.

[0046] The plane 11a where the end face of the first peripheral wall 11 is located serves as the contact surface between the water tank 10 and the base 20. When the water tank 10 is pulled out, the end face of the first peripheral wall 11 contacts the base 20. The water-blocking strip 31 is located within the receiving groove 10a enclosed by the first peripheral wall 11 and will not contact the base 20, thereby avoiding wear caused by friction between the end face of the water-blocking strip 31 and the base 20, which would affect the water-blocking effect.

[0047] It is understandable that when the first peripheral wall 11 is set as the peripheral sidewall / top of the water tank 10, it can prevent the water baffle 31 from contacting the humidifier housing and causing wear.

[0048] In some optional embodiments, the spring pin connector includes a pin seat, a spring pin disposed on the pin seat, and a first sealing ring sleeved on the pin seat; a mounting groove is provided on the back of the cover plate, and a clearance hole is provided at the bottom of the mounting groove for the elastic end of the spring pin to pass through; the pin seat is engaged in the mounting groove, and the first sealing ring is pressed tightly in the mounting groove by the seat body portion of the pin seat.

[0049] For example, refer to Figure 5-6 In this embodiment, a spring pin connector 40 includes a first pin seat 42, a first sealing ring 43, and two spring pins 41. The spring pins 41 are conventional spring pins, including a needle tube, a spring, and a needle shaft; specific details can be found in commercially available spring pins, which will not be elaborated upon here. The first pin seat 42 is made of insulating material, and the two spring pins 41 are tightly inserted into the first pin seat 42. A first flange 421 extending radially outward is provided on the bottom edge of the first pin seat 42. The first sealing ring 43 is fitted onto the first pin seat 42, and one sealing surface of the first sealing ring 43 abuts against the first flange 421. Two first mounting grooves 32 are provided on the back of the first cover plate 30. The two spring pin connectors 40 are respectively engaged in their corresponding first mounting grooves 32. The other sealing surface of the first sealing ring 43 abuts against the bottom wall of the first mounting groove 32 and is pressed tightly into the first mounting groove 32 by the first pin seat 42. Two clearance holes 33 are provided at the bottom of the first mounting groove 32, and the elastic ends 411 of the two spring pins 41 of the spring pin connector 40 pass through the clearance holes 33.

[0050] In this way, the spring pin connector 40 can achieve a sealing fit with the first cover plate 30 through the first sealing ring 43, preventing water outside the first cover plate 30 from entering the first cover plate 30 through the clearance hole 33.

[0051] In some alternative embodiments, a raised ring is provided in the mounting groove, and a clearance hole is located inside the raised ring.

[0052] For example, continue to refer to Figure 5-6 In this embodiment, a second mounting groove 35 is provided on the back of the first cover plate 30, and a first mounting groove 32 is disposed within the second mounting groove 35. A first circuit board 401 is disposed within the second mounting groove 35, and a spring pin connector 40 is connected to the first circuit board 401. The first circuit board 401 is locked within the second mounting groove 35 by screws. Thus, while fixing the first circuit board 401, the first sealing ring 43 fitted on the first pin seat 42 can be pressed tightly; the groove wall of the second mounting groove 35 surrounding the first circuit board 401 can provide protection for the first circuit board 401, preventing the edges of the first circuit board 401 from being squeezed by other structures.

[0053] A raised ring 34 is provided in the first mounting groove 32, surrounding the two clearance holes 33. When the first sealing ring 43 is compressed, the raised ring 34 can increase the contact area between the bottom surface of the first mounting groove 32 and the sealing surface of the first sealing ring 43, and increase the sealing effect of the first sealing ring 43 around the two clearance holes 33, preventing water on the surface of the first cover plate 30 from flowing through the clearance holes 33 to the back of the first cover plate 30, thus preventing water from entering the first circuit board 401 in the second mounting groove 35.

[0054] In some alternative embodiments, a peripheral wall is provided around the outer periphery of the cover plate, and a groove is recessed on the end face of the peripheral wall that contacts the water tank, and a second sealing ring is provided in the groove.

[0055] For example, see the figure. Figure 2 and 5 In this embodiment, the first cover plate 30 is located at the bottom of the water tank 10. There is an assembly gap between the first cover plate 30 and the water tank 10. When the bottom of the water tank 10 comes into contact with water, the water can easily flow along the assembly gap to the back side of the first cover plate 30, causing corrosion to the first circuit board 401 and the spring pin connector 40 installed on the back side, affecting normal use.

[0056] To this end, a second peripheral wall 36 is provided around the outer periphery of the first cover plate 30. A groove 37 is recessed on the end face of the second peripheral wall that contacts the water tank 10. A second sealing ring 301 is provided in the groove 37. A corresponding insertion part (not shown) is protruding from the bottom of the first cover plate 30 and corresponds to the groove 37. During assembly, the insertion part is aligned with the groove 37 and inserted into the groove 37 to press the second sealing ring 301. By compressing the second sealing ring 301, the assembly gap between the first cover plate 30 and the water tank 10 is sealed, preventing water adhering to the bottom of the water tank 10 from seeping into the back side of the first cover plate 30 through this assembly gap.

[0057] It is understandable that when the first cover plate 30 is installed on the periphery or top of the water tank 10, the sealing fit between the first cover plate 30 and the water tank 10 can also be achieved through the above-mentioned sealing structure.

[0058] In some alternative embodiments, screw holes are provided on the outer side of the peripheral wall, and the cover is locked to the water tank by screws passing through the screw holes.

[0059] For example, refer to Figure 5 and Figure 6 Six screw holes 38 are provided on the outer peripheral wall of the second peripheral wall 36 of the first cover plate 30. During assembly, the slot 37 of the first cover plate 30 is first pressed onto the insertion part at the bottom of the water tank 10, and then the screws 302 are tightened into the six screw holes respectively. The screws 302 are used to lock the first cover plate 30 to the bottom of the water tank 10, and the second sealing ring 301 in the slot 37 is pressed to ensure that the second sealing ring 301 is pressed to achieve effective sealing.

[0060] In some alternative embodiments, the cover is disposed on the outer wall of the bottom of the water tank.

[0061] For example, refer to Figure 2 In this embodiment, the first cover plate 30 is disposed on the outer wall of the bottom of the water tank 10. The first cover plate 30 is concealed at the bottom of the water tank 10, which can reduce the impact of the first cover plate 30 on the appearance of the water tank 10, making the water tank 10 look more concise and beautiful.

[0062] In some alternative embodiments, the water tank waterproof electrical connection structure further includes a conductive seat disposed on the base supporting the water tank, the conductive seat corresponding to the spring pin connector, and the contact end of the conductive seat protruding from the support surface of the base.

[0063] For example, refer to Figure 1 , Figure 3 and Figure 7 In this embodiment, the water tank 10 is provided with a base 20 supporting the water tank. The base 20 is provided with conductive seats 60 corresponding one-to-one with the four spring pin connectors 40. Each conductive seat 60 includes a second pin seat 62, a third sealing ring 63, and two conductive pins 61. The second pin seat 62 is made of insulating material, and the two conductive pins 61 are tightly inserted into the second pin seat 62. A second flange 621 extending radially outward is provided at the bottom edge of the second pin seat 62. The third sealing ring 63 is sleeved on the second pin seat 62, and one sealing surface of the third sealing ring 63 abuts against the second flange 621. Two third mounting grooves 51 are provided on the back of the second cover plate 50. The two conductive seats 60 are respectively engaged in their corresponding third mounting grooves 51. The other sealing surface of the third sealing ring 63 abuts against the bottom wall of the third mounting groove 53 and is pressed tightly into the third mounting groove 53 by the second pin seat 62. Two clearance holes are made at the bottom of the third mounting groove 53, and the contact end of the conductive seat 60 passes through the clearance holes and protrudes from the surface of the second cover plate 50.

[0064] In this embodiment, the second cover plate 50 is integrally formed with the base 20, and the conductive seat 60 can be installed from the bottom side of the base 20, eliminating the need for a sealing structure between the second cover plate 50 and the base 20.

[0065] In this embodiment, a fourth mounting groove 52 is provided on the back of the second cover plate 50, and a third mounting groove 51 is disposed within the fourth mounting groove 52. A second circuit board 601 is disposed within the fourth mounting groove 52, and a conductive base 60 is connected to the second circuit board 601. The second circuit board 601 is locked in the fourth mounting groove 52 by screws. In this way, while fixing the second circuit board 601, the third sealing ring 63 sleeved on the second pin seat 62 is pressed tightly, and the groove wall of the fourth mounting groove 52 provides protection for the second circuit board 601.

[0066] In this embodiment, the head of the second pin holder 62 protrudes from the surface of the second cover plate 50 along with the contact end of the conductive pin 61. When the water tank 10 is installed on the base 20, it ensures that the conductive holder 60 contacts the spring pin connector 40 to form an effective electrical contact. Secondly, the second pin holder 62 provides insulation protection for the conductive pin 61, preventing water accumulation on the base 20 from conducting electricity to adjacent or surrounding conductive pins 61 and causing a short circuit.

[0067] In particular, based on the roller 12 installed at the bottom of the water tank 10, the height of the first cover plate 10 relative to the base 20 is increased. By protruding the contact end of the conductive seat 60 out of the base 20, the height of the roller 12 can be supplemented, ensuring that the spring needle conductive seat 40 and the conductive seat 60 can form effective electrical contact.

[0068] Furthermore, based on the roller 12, two protrusions 13 are provided at the bottom of the water tank 10, and a recess 21 is provided on the base 20. Thus, after the water tank 10 is installed in place, the engagement of the two protrusions 13 and the recess 21 temporarily fixes the water tank 10, preventing the water tank 10 from moving relative to the base 20 under the action of the roller, which would cause the spring needle conductive seat 40 and conductive seat 60 to fail.

[0069] In some alternative embodiments, the water tank waterproof electrical connection structure also includes a wireless power supply module disposed on a base supporting the water tank.

[0070] For example, refer to Figure 2-4 Two wireless water pumps 80 are installed inside the water tank 10. A power receiving area 10b for the water tank and water pumps is recessed at the bottom of the water tank. Two wireless power supply modules 70 are installed in the area corresponding to the power receiving area 10b on the base 20. The two wireless power supply modules 70 are equipped with power supply coils, which can supply power to the two wireless water pumps 80. This power supply method eliminates the need for a separate power supply structure. There are no exposed connection ports between the water tank 10 and the base 20 at the water pump positions, eliminating the possibility of short circuits or leakage of the wireless water pumps 80 due to water getting into the water tank or base.
