Detailed Description

So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.

The disclosed embodiment provides a microswitch assembly 100, as shown in fig. 1-7, comprising:

a microswitch 110, the microswitch 110 having a switch button 111; and

a housing 120 configured to have an accommodating space 101, the accommodating space 101 having a microswitch 110 therein; and a notch 102 is formed on the housing 120, and the switch knob 111 of the micro switch 110 is located at the notch 102.

In the micro switch assembly of the embodiment of the present disclosure, the outer shell 120 is disposed outside the micro switch 110, so as to protect the micro switch 110. For example, the micro switch 110 is applied to a humidity adjusting device (e.g., a dehumidifier), the micro switch assembly is integrally assembled to the humidity adjusting device, and the housing 120 can form a sealed assembly with the humidity adjusting device, so that the problems of damage to the micro switch and electrical components inside the device when water in a water tank of the humidity adjusting device overflows can be effectively prevented.

In the disclosed embodiment, the switch button 111 of the microswitch 110 is located at the notch 102. Whether the switch button 111 protrudes from the housing 120 through the notch 102 is not limited as long as the switch button 111 can be touched. In some embodiments, the switch button 111 protrudes from the housing 120 through the notch 102. The switch button is convenient to trigger. I.e. the surface of the side of the housing 120 where at least part of the switch button 111 protrudes the indentation 102. In other embodiments, the end of the switch button 111 does not extend beyond the surface of the side of the housing 120 where the notch 102 is located. The assembly of the micro switch 110 and the housing 120 is facilitated and the malfunction is avoided to some extent.

In the embodiment of the present disclosure, the structure of the housing 120 is not limited as long as the accommodating space 101 is formed and the micro switch 110 is assembled in the accommodating space 101. In some embodiments, as shown in fig. 2, the outer shell 120 includes a first shell 121 and a second shell 122, the first shell 121 and the second shell 122 are snapped to form the outer shell 120; the first housing 121 has a notch 102 formed in a sidewall thereof. The housing 120 is configured to be opened and closed, which facilitates the assembly of the micro switch 110. Alternatively, the first housing 121 and the second housing 122 each have an open box shape.

The accommodating space 101 may be formed only on the first casing 121 or the second casing 122, and correspondingly, the second casing 122 or the first casing 121 may be a cover. The first casing 121 and the second casing 122 may have a certain accommodating space, and the two casings are fastened to form the accommodating space 101. The specific implementation is not limiting.

The notch 102 may be directly formed on the sidewall of the first housing 121, or may be formed by matching with the second housing 122.

In some embodiments, a cutout 1210 is formed in a side wall of the first housing 121. When the second housing 122 is fastened to the first housing 121, the notch 1210 and the edge of the fastening end (open end) of the second housing 122 form a notch 102. The assembly of the microswitch 110 is facilitated.

In some embodiments, the second shell 122 has a protrusion 1220 formed at a position corresponding to the notch 1210 of the first shell 121, and the shape of the protrusion 1220 is identical to the shape of the notch 1210. When the second shell 122 is fastened to the first shell 121, the protrusion 1220 of the second shell 122 is inserted into the opening 1210 of the first shell 121, and the protrusion 1220 blocks part of the opening 1210 to form the notch 102. When the depth of the notch 1210 is made deeper to accommodate the mounting position of the microswitch 110, the protrusion 1220 blocks part of the notch 1210, thereby reducing the area of the notch 102 and increasing the protection of the housing 120.

In some embodiments, the open ends of the first and second housings 121 and 122 are formed with a fastening structure configured to fasten the first and second housings 121 and 122. As shown in fig. 5 and 6, a fastening groove 1211 is formed on the open end of the first housing 121 (or the second housing 122), and accordingly, a fastening claw 1221 is formed on the open end of the second housing 122 (or the first housing 121). The buckling grooves 1211 and the buckling claws 1221 are matched in shape, and the buckling claws 1221 are buckled into the buckling grooves 1211 to form a buckling mode. The first case 121 and the second case 122 are not easily opened. Alternatively, the hooking claw 1221 is wedge-shaped such that the inclined surface of the wedge-shaped hooking claw 1221 faces the first housing 121 (or the second housing 122). The number and the positions of the fastening grooves 1211 and the fastening claws 1221 are not limited, and may be determined according to actual conditions.

In some embodiments, the microswitch 110 is disposed within the first housing 121, and the second housing 122 is snap fit to the open end of the first housing 121. The assembly is convenient.

In some embodiments, a seal is provided on the inner wall of the housing 120 circumferentially of the gap 102. The sealing structure is located between the inner wall of the housing 120 and the micro switch 110, so as to effectively prevent foreign matters from entering the housing 120 through the notch 102. For example, when the water tank is applied to a humidity adjusting device, such as a dehumidifier, when the dehumidifier is toppled, the water in the water tank can be more effectively prevented from entering the shell 120 from the notch 102 and then entering the interior of the dehumidifier. Optionally, the sealing structure is an elastic structure. Optionally, the resilient structure is a rubber gasket. A rubber gasket is provided on the inner wall of the housing 120 in the circumferential direction of the notch 102.

That is, the micro switch 110 is disposed in the receiving window 1301, and a portion of the micro switch on the side of the switch button 111 is located in the first chamber 1011, and a portion of the micro switch on the other side is located in the second chamber 1012. The support can be provided for the assembly of the micro switch 110 while sealing off foreign matters such as water or dust.

Optionally, the volume of the first cavity 1011 is smaller than the volume of the second cavity 1012. The second chamber 1012 located on the rear side of the apparatus is made large in volume, providing a larger accommodation (housing) space for wiring and the like of the micro switch 110.

Alternatively, as shown in fig. 5, 6 and 7, for the case structure when the case 120 includes the first case 121 and the second case 122, the partition 130 includes,

a first partition plate 131, the first partition plate 131 being formed in the first case 121;

and a second partition 132, the second partition 132 being formed in the second case 122.

When the first case 121 and the second case 122 are snapped, the first partition 131 and the second partition 132 are butted and form a receiving window 1301. The size of the receiving window 1301 is matched with the size of the microswitch 110, so that the microswitch 110 can be received and the microswitch 110 can be assisted to be fixed. And, the assembly is convenient.

While being caught, the microswitch 110 is also prevented from being inclined in the longitudinal direction and the like, and the switch knob 111 is prevented from being displaced.

When the microswitch 110 is assembled, the positioning column is inserted into the positioning hole, and after the positioning is in place, the clamping jaw of the clamping column is simultaneously buckled on the side wall of the microswitch 110 to clamp the microswitch 110, and the assembly is finished. After the housing 120 is fastened, the micro switch 110 is securely and stably transferred into the housing 120 by the auxiliary fixing function of the receiving window 1301 of the partition 130.

Optionally, the mounting structure 140 is disposed within a cavity of the first housing 121. And the mounting structure 140 is disposed at a position matching the opening position of the notch 1210 of the first housing 121. The switch button 111 is positioned in the notch 1210 after the microswitch 110 is assembled in the first housing 121.

In some embodiments, an extension plate 123 is formed on an edge of the side (first side 1201) where the notch 102 is located. I.e. the edges of the side where the indentation 102 is located extend out of the housing 120. The extension plate 123 serves to facilitate the assembly of the micro switch assembly to an exterior member (e.g., the support partition plate 310 of the dehumidifier 300 shown in fig. 13), and to cover the assembly joint of the outer case 120 facing the outside (e.g., the water tank 320 side) and the exterior member, thereby preventing foreign substances such as water or dust from passing through the joint.

One, two, three or four edges of the first side surface 1201 are provided with the extension plates 123, and the extension plates may be provided according to actual conditions. As shown in fig. 1 and 2, the extension plates 123 are provided on four edges of the first side surface.

In some embodiments, the microswitch assembly 100 further comprises an external structure formed on the housing 120 and configured to connect the microswitch assembly 100 to an external structure. The external connection structure is determined according to the external structural member connected to the external connection structure.

The micro switch assembly 100 is assembled to the support partition plate 310 of the dehumidifier 300, and an external structure with a plate body as an external structural member will be described. The external structure includes a fixing hole and/or a limiting slot 125.

In some embodiments, as shown in fig. 3-7, a wiring hole 126 is formed in the housing 120, and the wiring of the micro switch 110 is led out through the wiring hole 126. Optionally, the wiring hole 126 is located at the side of the second cavity 1012.

In practical applications, due to the small size of the switch button 111 of the micro switch 110, the switch button 111 is generally triggered by a touch rod, and the trigger action of the touch rod is triggered by the float 200. The structure of the touch bar is not limited, as long as the touch bar is configured to be movable when touched, and can press the switch button 111 of the micro switch 110 during the movement, and can touch the switch button 111 of the micro switch 110.

In the microswitch assembly 100 of the disclosed embodiment, a specific structure of the feeler lever is given, but not limited to the structure of the feeler lever. In some embodiments, as shown in fig. 2 and 4, the microswitch assembly 100 further comprises a stem 150 (i.e., a type of lever), the stem 150 being configured to rotate when depressed and to interfere with the switch button 111 of the microswitch 110 during rotation. The stem 150 is interposed between the float 200 and the micro switch 110, and controls the push or pop of the switch button 111 under the control of the float 200.

The specific structure and the manner of implementing the rotation of the stem 150 are not limited as long as the stem can abut against the switch knob 111 of the micro switch 110 when rotated. For example, this may be achieved by rotation about an axis, or in other ways.

In some embodiments, the stem 150 is rotatably coupled to the housing 120, and when the stem of the stem 150 is naturally resting (under only gravity), at least a portion of the stem can contact the switch button 111 to ensure that the switch button 111 of the microswitch 110 is pressed during rotation.

In some embodiments, the handle 150 is rotatably coupled to the housing 120 by a shaft engaging a shaft hole. As shown in fig. 2 and 4, a rotating shaft 151 is disposed at one end of the rotating handle 150, a shaft hole seat 127 is disposed on the housing 120, and a shaft hole 1270 is disposed on the shaft hole seat 127. The rotating shaft 151 of the rotating handle 150 is movably connected in the shaft hole 1270. The stem 150 is pivotally connected to the housing 120.

In some embodiments, the stem 150 is attached to the housing 120 by a resilient tab to effect rotational displacement. Alternatively, one end of the elastic piece is provided on the housing 120 and the other end is connected to the stem 150. When the elastic piece is in a natural extension state, the rotating handle 150 does not press (but can contact) the switch button 111; when the stem 150 is pressed, the elastic piece deforms to rotate the stem 150, contacting and pressing the switch button 111 of the micro switch 110. Alternatively, the stem 150 itself may be a resilient sheet.

The rotary handle 150 is rotated to abut against the switch knob 111, and at least a part of the handle body of the rotary handle 150 can contact the switch knob 111 when the rotary handle 150 is naturally placed. Alternatively, when the rotary handle 150 is pressed and rotated, at least a part of the handle body can contact the switch button 111. The structure of the stem 150 may be designed accordingly according to the arrangement of the switch button 111. In some embodiments, the stem 150 has a post 152 thereon. When the rotating handle 150 is naturally placed, the convex column 152 can be contacted with the switch button 111; alternatively, when the rotating handle 150 is pressed and rotated, the protruding column 152 can contact the switch button 111 and press the switch button 111.

In some embodiments, the axis of rotation of the stem 150 is located on the upper side of the switch button 111 of the microswitch 110. The upper side here is defined as the view angle in normal use after the microswitch assembly has been assembled, as shown in fig. 2 and 4. At this time, the pressed end of the stem 150 is located at the lower side of the switch button 111. When the micro-switch assembly 100 with the structure is applied to humidity adjusting equipment such as a dehumidifier, the position of the micro-switch 110 relative to the floater 200 can be raised, and when the water tank is full of water and overflows, water can be further prevented from entering the micro-switch assembly 100, and electric appliance elements are prevented from being damaged.

In some embodiments, the struck portion 1501 of the stem 150 has a curved surface that is convex away from the microswitch 110. As shown in fig. 4, the touched portion 1501 of the stem 150 is the end portion of the stem body of the stem 150. Alternatively, the touched portion 1501 of the stem 150 is located at the distal end portion of the stem body. The tail end part of the handle body is integrally arc-shaped. The touched portion 1501 of the stem 150 is in touch contact with an external touch member (e.g., the first end 201 of the float 200) in a line-to-plane, line-to-line, line-to-point, point-to-plane, point-to-line, or point-to-point manner, which reduces friction, increases touch sensitivity, and increases the sensitivity of the float switch device.

The disclosed embodiment provides a float switch device, including,

the microswitch assembly 100 described above, and

a float 200, the float 200 including a first end 210; the float 200 is provided to be rotatable, and by the rotation, an end surface of the first end 210 of the float 200 can be brought close to or away from the switch knob 111 of the micro switch 110, thereby controlling the push-in or pop-out of the switch knob 111.

The float switch device of the embodiment of the present disclosure realizes the on/off of the micro switch through the rotation of the float 200 generated under the buoyancy, and can be applied to a humidity adjusting device with liquid level change, such as a dehumidifier or a humidifier. Meanwhile, due to the structure of the micro-switch assembly 100, the phenomenon that liquid overflows when the liquid overflows due to abnormal conditions such as toppling of the equipment can be effectively avoided.

In the disclosed embodiment, the first end 210 of the float 200 may directly contact and control the switch button 111, or may indirectly control the switch button 111 through the stem 150.

In some embodiments, when the microswitch assembly 100 comprises the stem 150, the stem 150 (the touched portion 1501 of the stem 150) contacts the end surface of the first end 210 of the float 200 and is movable with the movement of the first end 210 of the float 200 and contacts the switch button 111 of the microswitch 110 during the movement.

When the float 200 rotates to make the first end 210 close to the micro switch 110, the end surface of the first end 210 touches and presses the rotating handle 150, so that the rotating handle 150 also rotates towards the micro switch 110, the rotating handle 150 (the convex column 152) butts against the switch button 111, the switch button 111 is pressed in, and the micro switch 110 is switched on. At this time, the stem 150 is simultaneously pressed by the first end 210 and the switch button 111, but the contact pressure of the first end 210 is greater than the contact pressure (spring force) of the switch button 111, so that the stem 150 presses the switch button 111 in.

When the float 200 reversely rotates to make the first end 210 far away from the microswitch 110 on the basis that the first end 210 presses the switch button 11, the contact pressure applied to the rotating handle 150 by the first end 210 disappears, that is, the contact pressure to the switch button 111 is cancelled, the switch button 111 starts to rebound and pushes the rotating handle 150 to far away, and the rotating handle 150 abuts against the first end 210 and moves synchronously with the first end 210. As the reverse rotation of the float 200 proceeds, the first end 210 rotates and moves away until the switch knob 111 is completely ejected and the micro switch 110 is turned off.

The float switch device of the embodiment of the present disclosure, under the buoyancy, by the rotation of the float 200, the first end 210 may be close to or far from the micro switch 110, so that the rotation handle 150 is close to or far from the micro switch 110, thereby completing the pressing or bouncing of the switch button 111 of the micro switch 110. In practical applications, depending on the equipment to which it is applied, it is sufficient to control the manner of assembling the float switch device and the initial position states of the float 200 and the micro switch 110.

When the float 200 rotates while moving up (or down) due to the difference in the initial engagement position between the float 200 and the microswitch assembly 100, the distance between the end surface of the first end 210 of the float 200 and the switch button 111 of the microswitch 110 changes differently (approaches or departs), thereby realizing different switch controls of the microswitch 110.

For example, when applied to a dehumidifier 300 to control the operation of the dehumidifier, the float switch device is assembled to the dehumidifier 300 such that the initial position state of the float switch device is (as shown in fig. 13): the floater 200 touches and presses the rotating handle 150 without the action of buoyancy, so that the rotating handle 150 is pressed against the switch button 111, and the switch button 111 is in a pressed-in state; and the first end 210 of the float 200 is below the plane of the rotational axis of the float 200. In the initial position, the micro switch 110 is turned on, and the dehumidifier 300 can be normally turned on/off. When the water level in the water tank rises and approaches the preset height, the floater 200 can move upwards under the action of buoyancy to rotate, the first end 210 of the floater synchronously rotates downwards, the first end 210 is far away from the micro switch 110, the switch button 111 pops up and presses the rotating handle 150, the rotating handle 150 further abuts against the first end 210 of the floater 200, and the popping state of the switch button 111 of the micro switch 110 is controlled. As the water level further rises, the first end 210 is more and more away from the micro switch 110 until the switch progress of the switch button 111 of the micro switch 110 is reached, and the switch button 111 is fully sprung, as shown in fig. 14. At this time, the dehumidifier 300 cannot be normally started up, and the water in the water tank 320 needs to be treated before the dehumidifier can be normally started up.

When applied to the humidifier, the change in water level is reversed, and the float 200 rotates in the opposite direction and the first end moves in the opposite direction. Therefore, the initial position state of the float switch device may be determined according to the actual control method.

Therefore, the distance between the first end 210 and the micro switch 110 is changed during the rotation of the float 200, and thus, the change of the distance is used to control the initial position state of the float switch device and the change of the rotation direction of the float caused by the water level change, thereby realizing the control of the humidity control device or the water full/short alarm.

In some embodiments, the end surface of the first end 210 of the float 200 is an arcuate end surface. The contact between the arc end surface 201 of the first end 210 of the float 200 and the switch button 111 or the rotating handle 150 can be line-surface, line-line, line-point, point-surface, point-line, point-point, etc., so that the friction force is reduced, and the contact sensitivity is improved.

The specific structure of the arcuate end surface of the first end 210 of the float 200 is not limited. The arc-shaped end surface may be a spherical arc surface or an arc surface (as shown in fig. 8, the first end 210) in an arc line.

Optionally, the front end of the arcuate plate 211 presents a rounded tip 2110 that winds inward. It is ensured that the positions of the first end 210 of the float 200, which can contact with the external member, are all curved.

Alternatively, the arc plate 211 is formed by bending a plate-shaped profile. Is simple and easy to obtain.

In some embodiments, the first end 210 further comprises ribs 212, the ribs 212 being disposed on the concave sides of the arcuate plate 211. The arc-shaped plate 211 is supported to enhance the strength of the arc-shaped plate 211.

Optionally, the plate surface of the rib plate 212 is perpendicular to the concave side surface of the arc plate 211.

Optionally, the arcuate plate 211 and the rib 212 are integrally formed.

The arc degree and the arc length of the arc-shaped end surface of the first end 210 are not limited, and are determined according to factors such as the assembly position, the stroke of a switch button of a matched microswitch and the like. For example, the stroke of the switch button is long, and the arc length of the arc end surface is longer; on the contrary, the stroke of the switch button is short, and the arc length of the arc end surface is short.

In some embodiments, the depressed portion 151 of the stem 150 of the microswitch assembly 100 is disposed opposite the arcuate end surface of the first end 210 of the float 200.

Thus, the float 200, as shown in FIG. 8, further includes a second end 220 that is floatable, i.e., capable of floating on the surface of the liquid. When the liquid level changes, the second end 220 is also displaced. For example, as the liquid level increases, the second end 220 rotates upward about the rotational axis of the float 200, and the first end 210 rotates downward about the rotational axis of the float 200. Thereby changing the distance between the end surface of the first end 210 and an external actuated member (e.g., the switch button 111 or the stem 150 of the microswitch assembly 100) to thereby enable the switch button 111 to be pushed in or pushed out.

In some embodiments, as shown in fig. 9, the second end 220 of the float 200 includes a lightweight member 221, the lightweight member 221 being removably disposed on the second end 220 of the float 200.
