Description

Technical Field

[0001] This utility model belongs to the field of switch controller technology, specifically relating to a push-type temperature control switch. Background Technology

[0002] Liquid expansion protectors typically consist of a temperature bulb and a touch switch. They utilize the principle of thermal expansion and contraction of the liquid within the temperature bulb to control the contact or separation of the metal plate of the touch switch, thereby switching the touch switch on and off and achieving the protection purpose. However, this type of liquid expansion protector can only control the reciprocating motion of the metal plate through the temperature bulb, and this control structure is not suitable for rotary switches or rotary valve devices.

[0003] Utility model application No. 202123026021.5 discloses a temperature control switch with multiple temperature sensors, comprising: at least two temperature sensors, both connected to a diaphragm box; and a switching mechanism linked to the diaphragm box via a push rod assembly. When the ambient temperature of one of the temperature sensors exceeds a preset value, the diaphragm box expands, thereby driving the switching mechanism to cut off the circuit via the push rod assembly. However, this temperature control switch only has the function of driving a reed to swing and cannot control rotary switches or valve-like structures. Summary of the Invention

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] A push-type temperature control switch is used to adapt to a switch handle 1 of a switch or valve structure, driving the switch handle 1 to rotate. This push-type temperature control switch includes a housing 2 and a push-moving component 3 and a temperature sensing bulb 4 arranged inside the housing 2. The temperature sensing bulb 4 is connected to the push-moving component 3, driving the push-moving component 3 to move along the inner wall of the housing 2. A rotary guide structure 5 is provided inside the push-moving component 3. The switch handle 1 is slidably connected in the rotary guide structure 5. The relative position between the switch handle 1 and the housing 2 is fixed. When the temperature sensing bulb drives the push-moving component 3 to move, the rotary guide structure 5 moves relative to the switch handle 1, thereby causing the switch handle 1 to rotate along the rotary guide structure 5.

[0027] In this embodiment, the temperature sensing bag 4 includes a paraffin bag 4-1 and a push rod 4-2. The push rod 4-2 abuts against the pusher 3. The volume of the paraffin bag 4-1 can change with temperature. The volume change of the paraffin bag 4-1 drives the push rod 4-2 to push out or retract, thereby moving the pusher 3.

[0028] The rotary guide structure 5 includes a spiral groove 5-1 and a guide groove 5-2. The spiral groove 5-1 is spiral-shaped, and the spiral angle of the spiral groove 5-1 is 90°-180°. That is, when the switch handle 1 moves from the bottom to the top of the spiral groove 5-1 under the action of the spiral groove 5-1, the rotation angle of the switch handle 1 is 90°-180°. The guide groove 5-2 is connected to the bottom of the spiral groove 5-1 and is arranged parallel to the axis of the housing 2. That is, when the switch handle 1 moves in the guide groove 5-2, the switch handle 1 does not rotate. That is, the amount of movement of the push rod 4-2 caused by the change in ambient temperature is less than or equal to the length of the guide groove 5-2. When the amount of movement of the push rod 4-2 caused by the change in ambient temperature is greater than or equal to the length of the guide groove 5-2, the switch handle 1 moves into the spiral groove 5-1 and rotates through the spiral groove 5-1.

[0029] In this embodiment, the switch handle 1 is provided with a guide post 1-1, which is slidably installed in the rotary guide structure 5, thereby driving the switch handle 1 to rotate through the rotary guide structure 5.

[0030] To facilitate the repositioning of the pusher 3, a spring 7 is provided between the pusher 3 and the housing 2. The spring 7 and the temperature sensing bulb 4 are respectively arranged on both sides of the pusher 3. The temperature sensing bulb 4 drives the pusher 3 to push outward, and the spring 7 drives the pusher 3 to retract and reset.

[0031] The housing 2 includes an upper housing 2-3 and a lower housing 2-4 welded by ultrasonic welding. An installation groove 2-5 is provided on the inner side of the upper housing 2-3. The temperature sensing bulb 4 is fixed in the upper housing 2-3 through the installation groove 2-5. The lower housing 2-4 is provided with a first hole section 2-1 and a second hole section 2-2. The first hole section 2-1 is connected to the upper housing 2-3. A guide part 2-6 is provided on the inner wall of the first hole section 2-1. The guide part 2-6 is a sliding groove parallel to the axis of the housing 2. Its opening is located at the end of the first hole section 2-1 to facilitate the installation of the guide head 3-2 of the pusher 3 into the guide part 2-6.

[0032] The pusher 3 is a columnar structure. A guide ring 3-1 is provided on the outer side wall of the pusher 3 and is slidably installed in the housing 2. A guide head 3-2 is provided on the outer side of the guide ring 3-1 and is slidably connected to the guide part 2-6. The pusher 3 is guided to slide by the guide head 3-2.

[0033] The circumferential sidewall of the guide ring 3-1 is slidably connected to the inner wall of the first hole section 2-1, and the circumferential sidewall of the pusher 3 is slidably connected to the inner wall of the second hole section 2-2, ensuring the stability of the movement of the pusher 3. At the same time, the guide part 2-6 provides guidance for the movement of the pusher 3, preventing the pusher 3 from rotating during the movement, and ensuring that the pusher 3 can stably drive the switch handle 1 to rotate.

[0034] To ensure the connection stability between the temperature sensing bulb 4 and the pusher 3, a connection hole 3-3 is provided on the top of the pusher 3. The temperature sensing bulb 4 is connected to the connection hole 3-3, ensuring that the push rod 4-2 abuts against the middle of the pusher 3, and ensuring that the force of the push rod 4-2 is distributed in the middle of the pusher 3.

[0035] A viewing window 2-7 is provided on the top of the upper housing 2-3, and an observation post 3-4 is provided on the top of the pusher 3. The observation post 3-4 is inserted into the viewing window 2-7. The relative position of the observation post 3-4 and the viewing window 2-7 is used to detect whether the pusher 3 has moved.

[0036] A connecting end cover 6 is rotatably installed on the outside of the lower housing 2-4. A limiting ring 2-8 is provided at the bottom of the lower housing 2-4. The connecting end cover 6 abuts against the upper part of the limiting ring 2-8. The lower housing 2-4 is installed on the switch and valve body structure through the connecting end cover 6, so that the position of the housing 2 and the switch handle 1 is fixed.
