Description

Technical Field

[0001] The utility model relates to the field of temperature controllers, and more specifically, to an insertion type temperature controller. Background Art

[0002] A plug-in thermostat is a circuit temperature control unit used in various types of electric kitchen appliances. It generally has a probe and a temperature control switch that matches the probe. The probe transmits heat information to the temperature control switch, thereby controlling whether the current can pass through the temperature control switch. When working, the plug-in thermostat is plugged into the electrical appliance. However, when the kitchen appliances need to be cleaned, the plug-in thermostat needs to be removed. The plug-in thermostat, which is fixed to the kitchen appliances only by friction, needs to be subjected to increased force during the disassembly and assembly process. Moreover, with repeated plugging and unplugging, the friction force decreases and it is easy to loosen.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a plug-in temperature controller.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a plug-in temperature controller, comprising a shell, a mounting seat, and a probe fixedly connected to the shell, the probe passes through the mounting seat, and one end of the shell close to the probe is embedded in the mounting seat, the shell and the mounting seat are detachably connected, a limiting groove is provided on the top surface of the mounting seat, a limiting block is slidably connected to the shell, a lifting spring is fixedly connected to the inner bottom surface of the shell, the top of the lifting spring is fixedly connected to the limiting block, the limiting block is slidably connected in the limiting groove, a chamfered surface is provided between the side wall of the limiting block and the top surface of the limiting block, the bottom end of the chamfered surface is higher than the bottom end of the limiting groove, the height difference between the two ends of the chamfered surface is greater than the depth of the limiting groove, and the chamfered surface is located on the side of the limiting block away from the probe.

[0006] The utility model is further configured as follows: along the direction away from the probe, the thickness of the side wall of the limiting groove away from the probe gradually decreases.

[0007] The utility model is further configured as follows: a guide hole is opened on the inner side wall of the mounting seat, the length direction of the guide hole is the same as the length direction of the probe, an ejection spring is fixedly connected to the bottom surface of the guide hole, and the extension direction of the ejection spring is the same as the length direction of the guide hole.

[0008] The utility model is further configured as follows: a circular arc transition is formed between the side wall of the limit block close to the probe and the top surface of the limit block.

[0009] The utility model is further configured as follows: the guide holes are symmetrically arranged on both sides of the probe.

[0010] The utility model is further configured as follows: the mounting seat is made of heat insulating material.

[0011] In summary, the utility model has the following beneficial effects: the movement between the shell and the mounting seat is limited by the cooperation of the limit groove and the limit block, and the mounting seat is fixed on the mounting plane of the electrical appliance, thereby avoiding loosening of the shell and the probe and ensuring the connection strength between the thermostat and the mounting plane. The shell itself is small in size, and pressing the limit block and sliding the shell can be done with one hand, which is relatively convenient. The HPL material has good thermal insulation performance, which avoids the difficulty of plugging and unplugging the shell due to the heat of the electrical appliance being transferred to the shell.

[0016] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Embodiment: A plug-in thermostat, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a shell 1, a mounting seat 3, and a probe 2 fixedly connected to the shell 1, the probe 2 passes through the mounting seat 3, and one end of the shell 1 close to the probe 2 is embedded in the mounting seat 3, the shell 1 and the mounting seat 3 are detachably connected, a limiting groove 4 is provided on the top surface of the mounting seat 3, a limiting block 5 is slidably connected to the shell 1, a lifting spring 6 is fixedly connected to the inner bottom surface of the shell 1, the top of the lifting spring 6 is fixedly connected to the limiting block 5, the limiting block 5 is slidably connected in the limiting groove 4, a chamfered surface 7 is provided between the side wall of the limiting block 5 and the top surface of the limiting block 5, the bottom end of the chamfered surface 7 is higher than the bottom end of the limiting groove 4, the height difference between the two ends of the chamfered surface 7 is greater than the depth of the limiting groove 4, the chamfered surface 7 is located on the side of the limiting block 5 away from the probe 2, and the mounting seat 3 adopts a heat-insulating material.

[0018] Specifically, the mounting base 3 is made of HPL material, and ears for fixed connection with the mounting surface are integrally formed on both sides of the mounting base 3. The outer surface of the shell 1 fits with the inner surface of the mounting base 3, and the shell 1 is slidably connected in the mounting base 3. The cross-section of the limit groove 4 is rectangular, and the bottom of the limit block 5 is arched. The limit block 5 spans above the probe 2. The lifting spring 6 is a vertically arranged compression spring. The two lifting springs 6 are symmetrically arranged on both sides of the probe 2, and the limit block 5 slides in the vertical direction.

[0019] The mounting seat 3 is mounted on the mounting plane. When the lifting spring 6 is in the lifting state, the inner side wall of the limiting groove 4 away from the probe 2 contacts the side wall of the limiting block 5, preventing the shell 1 from detaching from the mounting seat 3. The limiting block 5 is pressed and the shell 1 is slid outward. The chamfered inclined surface 7 contacts the side wall of the limiting groove 4 to guide the limiting block 5 to continue to slide downward, and the shell 1 is detached from the mounting seat 3. When inserting the shell 1, the probe 2 is first inserted into the mounting seat 3, and then the limiting block 5 is pressed, and the shell 1 is slid until the limiting block 5 is in the lifting state. It bounces up under the action of the spring 6, and the movement between the shell 1 and the mounting seat 3 is limited by the cooperation of the limit groove 4 and the limit block 5. The mounting seat 3 is fixed on the mounting plane of the electrical appliance, which avoids the loosening of the shell 1 and the probe 2 and ensures the connection strength between the thermostat and the mounting plane. The shell 1 itself is small in size, and pressing the limit block 5 and sliding the shell 1 can be done with one hand, which is more convenient. The HPL material has good heat insulation performance, which avoids the difficulty of plugging and unplugging the shell 1 due to the heat of the electrical appliance being transferred to the shell 1.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, along the direction away from the probe 2, the thickness of the side wall of the limit groove 4 away from the probe 2 gradually decreases, and a guide hole 8 is opened on the inner wall of the mounting seat 3, and the length direction of the guide hole 8 is the same as the length direction of the probe 2. The bottom surface of the guide hole 8 is fixedly connected with an ejection spring 9, and the extension and contraction direction of the ejection spring 9 is the same as the length direction of the guide hole 8. There is an arc transition between the side wall of the limit block 5 close to the probe 2 and the top surface of the limit block 5, and the guide holes 8 are symmetrically arranged on both sides of the probe 2.

[0021] Specifically, the wall thickness change of the limit groove 4 forms an inclined plane. When the shell 1 is pulled out, the lifting spring 6 causes the limit block 5 to squeeze the inclined plane and apply an outward force to the shell 1. When the shell 1 is inserted, the limit block 5 gradually descends along the inclined plane, that is, the lifting spring 6 is gradually compressed, reducing the resistance of inserting the shell 1, and cooperating with the rounded corner of the limit block 5 close to the probe 2 side, so that the insertion of the shell 1 is smoother. A cap is welded at the end of the ejection spring 9. The length of the cap is equal to the depth of the guide hole 8, and the outer diameter of the cap is smaller than the inner diameter of the guide hole 8. The ejection spring 9 provides an active thrust when the shell 1 is taken out. After pressing the limit block 5, under the action of the ejection spring 9, the shell 1 automatically pops out, further simplifying the operation of taking out the shell 1. The guide hole 8 cooperates with the cap to limit the movement trajectory of the ejection spring 9, and the ejection springs 9 symmetrically arranged on both sides of the probe 2 make the ejection trajectory of the shell 1 fit the length direction of the probe 2 to avoid jamming.

[0022] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
