For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0024] The following combination Figures 1 to 3 , the instant heating thermostat of this application is described in detail.

[0025] Reference Figures 1 to 3The embodiment of the present application provides an instant heating thermostat, including: a base 100, provided with a positioning block 110, the positioning block 110 is used to cooperate with the positioning groove of the external component; a power connection mechanism, provided on the base 100, the power connection mechanism includes a movable contact piece 210 and a static contact piece 220, the movable contact piece 210 is located below the static contact piece 220, the movable contact piece 210 and the static contact piece 220 are respectively connected to a spring terminal 230, and the spring terminal 230 is used to contact and connect with the thick film heating plate; a temperature sensing mechanism, connected to the movable contact piece 210, the temperature sensing mechanism is close to the thick film heating plate, and the temperature sensing mechanism can drive the movable contact piece 210 and the static contact piece 220 to contact or separate.

[0026] During installation, align the instantaneous thermostat with the mounting position of the thick-film heating plate. Then, press the external component against the thermostat and connect it to the thick-film heating plate. The positioning block 110 is now embedded in the positioning slot, and the spring terminal 230 is in contact with the circuit on the thick-film heating plate, thus completing the installation and fixation of the instantaneous thermostat. During operation, the moving contact 210 and the stationary contact 220 are in contact and connected, completing the circuit and allowing the thick-film heating plate to heat. When the temperature reaches the set temperature of the temperature sensing mechanism, the temperature sensing mechanism drives the moving contact 210 and the stationary contact 220 apart, disconnecting the circuit and causing the thick-film heating plate to stop heating.

[0027] By providing a positioning block 110, when the external component is connected to the thick film heating disk, the positioning block 110 will cooperate with the positioning groove of the external component, so that the external component presses the instant heating thermostat onto the thick film heating disk, thereby achieving the fixation of the instant heating thermostat. The structure is simple and the operation is easy. At the same time, the position of the instant heating thermostat can also be restricted to prevent the instant heating thermostat from rotating, thereby improving stability and reliability. By providing a spring terminal 230, when the external component presses the instant heating thermostat toward the thick film heating disk, the spring terminal 230 can firmly contact the thick film heating disk, which is convenient for circuit connection and improves work efficiency.

[0028] Reference Figure 2 , wherein a plurality of positioning blocks 110 are provided, and a plurality of positioning blocks 110 are integrally arranged on the base 100. Correspondingly, the external component is provided with a plurality of positioning grooves, and the positioning grooves correspond one-to-one to the positioning blocks 110. By cooperating with the plurality of positioning blocks 110 and the plurality of positioning grooves, the stability and reliability of the installation can be improved. In the present embodiment, two positioning blocks 110 are provided, and the two positioning blocks 110 are symmetrically arranged at the bottom of the base 100. Of course, three or four positioning blocks 110 can also be provided. For the number of positioning blocks 110, those skilled in the art can make a reasonable choice according to actual conditions, and this application does not impose any restrictions on this.

[0029] It can be imagined that the base 100 is provided with a jack, which is used to set a pin. At this time, the pin can be inserted into the base 100 from the jack to press the moving contact piece 210, so that the moving contact piece 210 contacts the static contact piece 220 to achieve circuit conduction. The structure is simple and the operation is easy.

[0030] Reference Figures 1 to 3 In this embodiment, the temperature sensing mechanism includes a bimetallic strip 310 and a top rod 320. The bimetallic strip 310 is arranged above the base 100. One end of the top rod 320 is connected to the bimetallic strip 310, and the other end of the top rod 320 is connected to the moving contact piece 210. The bimetallic strip 310 is used to tightly adhere to the thick film heating plate to deform due to heat, so that the top rod 320 drives the moving contact piece 210 and the static contact piece 220 to separate. During operation, the moving contact piece 210 and the static contact piece 220 are in contact, at which time the circuit is turned on and the thick-film heating disk is heated; when the temperature reaches the set temperature of the bimetallic strip 310, the bimetallic strip 310 will deform to protrude 240 toward the side of the push rod 320, causing the push rod 320 to descend to press the moving contact piece 210, and the moving contact piece 210 and the static contact piece 220 will separate. At this time, the circuit is disconnected and the thick-film heating disk stops heating; as the temperature drops, the bimetallic strip 310 gradually returns to its original shape, causing the push rod 320 to rise, the moving contact piece 210 and the static contact piece 220 to contact again, the circuit is turned on, and the thick-film heating disk starts heating again.

[0031] As can be imagined, the base 100 is provided with a guide frame 120, the bimetallic strip 310 is positioned above the guide frame 120, and the guide frame 120 is provided with a guide hole 130. The push rod 320 is inserted into the guide hole 130 and connected to the movable contact piece 210. The provision of the guide frame 120 can guide the movement of the push rod 320, preventing it from deflecting, improving stability and enhancing safety. It is easy to understand that the groove provided in the guide frame 120 ensures that the bimetallic strip 310 has sufficient operating space, ensuring the stability and reliability of the bimetallic strip 310.

[0032] It is easy to understand that the base 100 and the guide frame 120 can be installed by means of threads or by screws. Regarding the connection between the base 100 and the guide frame 120, those skilled in the art can make a reasonable choice based on actual conditions, and this application does not impose any restrictions on this.

[0033] Reference Figures 1 to 3In some embodiments, the temperature sensing mechanism further includes a temperature sensing cap 330, which is located above the bimetallic strip 310, in contact with the bimetallic strip 310, in close contact with the thick film heating plate, and connected to the base 100. The temperature sensing cap 330 can be made of copper or aluminum. Furthermore, the temperature sensing cap 330 is configured to be made of copper. By configuring the temperature sensing cap 330 to be made of copper, the temperature sensing cap 330 made of copper has a higher thermal conductivity than the temperature sensing cap 330 made of aluminum, which can allow heat to be transferred to the bimetallic strip 310 faster through the temperature sensing cap 330, so that the bimetallic strip 310 can sense temperature changes faster, and has higher detection accuracy for temperature detection during extreme heating, so that the bimetallic strip 310 can respond to temperature changes in a timely manner.

[0034] Of course, a through hole may also be provided in the middle of the temperature sensing cap 330 . In this case, the middle of the bimetallic strip 310 extends out of the through hole, so that the bimetallic strip 310 directly contacts the temperature-measured portion, thereby improving the stability and reliability of the bimetallic strip 310 .

[0035] In some embodiments, the spring terminal 230 is provided with a protrusion 240, which is used to contact and connect with the thick film heating plate. The protrusion 240 facilitates the contact and connection between the spring terminal 230 and the thick film heating plate, thereby improving stability and reliability.

[0036] It is easy to understand that the moving contact 210 is provided with a moving contact 250, and the stationary contact 220 is provided with a stationary contact 260, and the moving contact 250 can contact or separate with the stationary contact 260. During operation, the moving contact 210 and the stationary contact 220 are connected by the moving contact 250 and the stationary contact 260, at which time the circuit is conducted and the thick film heating plate is heated; when the temperature reaches the set temperature of the bimetallic strip 310, the bimetallic strip 310 will deform to protrude 240 toward the side of the top cover, causing the top rod 320 to descend to press the moving contact 210, and the moving contact 250 and the stationary contact 260 will separate, at which time the circuit is disconnected and the thick film heating plate stops heating; as the temperature drops, the bimetallic strip 310 gradually returns to its original shape, causing the top rod 320 to rise to release the moving contact 210, and the moving contact 250 and the stationary contact 260 will re-contact, the circuit is conducted, and the thick film heating plate starts heating again. By adopting the above structure, the connection between the moving contact piece 210 and the stationary contact piece 220 is facilitated, thereby improving stability and reliability.
