Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a temperature control device. Background Technology

[0002] With the popularization of the smart home concept and consumers' increasing demands for quality of life, adjustable thermostats, as a key temperature control device, are increasingly widely used in modern homes. These thermostats can freely adjust the set temperature according to the user's actual needs and automatically open or close the circuit when the preset temperature is reached through an internal mechanism, thereby maintaining the temperature of the environment or product within a constant range. They not only provide ideal temperature control functions but also help achieve efficient energy use, and are therefore widely used in household appliances such as electric heaters, water heaters, microwave ovens, electric ovens, and fireplaces.

[0003] However, despite the numerous advantages of these thermostats, the stepless rotary switch design used in many thermostats on the market today presents significant user experience drawbacks. This type of knob lacks a clear tactile feedback during rotation, making it difficult for users to make precise temperature adjustments. Furthermore, the lack of immediate feedback means users cannot accurately determine whether the current setting meets their needs, further impacting the user experience. Utility Model Content

[0004] To address the aforementioned problems, this invention discloses a temperature control device that provides users with better operational feedback and more precise temperature control capabilities.

[0005] To achieve the above objectives, the present invention provides a temperature control device installed on a small household appliance. The device includes a switch head, a thermostat, and a body. The switch head has an outer gear ring at its top. The body has a spring piece that abuts against and engages with the outer gear ring, limiting the position of the switch head. When the switch head is rotated, the outer gear ring rotates synchronously, causing the spring piece to elastically displace within the outer gear ring. One end of the thermostat is fixedly connected to the switch head, and the other end extends into the body.

[0006] Furthermore, the spring includes a support section and a U-shaped elastic arm. One end of the support section is bent upward to form a first vertical portion, and the end of the first vertical portion is bent upward to form an elastic section. The elastic section has an inclined arm that is inclined at an angle to the first vertical portion. The end of the inclined arm away from the elastic section extends downward and bends to form an abutment portion. The other end of the support section is bent downward to form a second vertical portion, and the end of the second vertical portion is connected to one end of the U-shaped elastic arm.

[0007] Furthermore, the top of the body is provided with a first placement edge and a second placement edge, which together form an installation channel. The support section is located within the installation channel. The ends of the first and second placement edges facing the thermostat are bent outward to form a snap-fit ​​portion. The first end of the abutment portion is snapped into the snap-fit ​​portion. The end away from the snap-fit ​​portion is provided with a hollow installation groove, and the U-shaped elastic arm is located within the installation groove.

[0008] Furthermore, a mounting base is provided with an upward protrusion at the middle position of the switch head, and the thermostat is located inside the mounting base.

[0009] Furthermore, the material of the spring is iron wire.

[0010] The beneficial effects of this utility model are:

[0011] This invention provides a temperature control device that uses an outer gear ring on the top of the switch head to cooperate with a spring plate fixed inside the machine body to achieve segmented adjustment of the rotation angle, making temperature adjustment more precise. Simultaneously, the tactile and audible feedback generated during rotation (such as a "click, click" sound) allows the user to clearly perceive each gear change, improving intuitiveness and user satisfaction. This temperature control device is not only simple in structure and easy to manufacture, but also safe and reliable in use, facilitating its implementation and widespread application.

[0022] This utility model proposes a temperature control device.

[0023] In the embodiments of this utility model, such as Figure 1-7 As shown, this temperature control device, installed on a small household appliance, includes a switch head 1, a thermostat 2, and a body 3. The top of the switch head 1 has an outer gear ring 11, and the body 3 has a spring piece 4 that abuts against and locks the outer gear ring 11 to limit the switch head 1. When the switch head 1 is rotated, the outer gear ring 11 is rotated synchronously, thereby causing the spring piece 4 to elastically displace within the outer gear ring 11. One end of the thermostat 2 is fixedly connected to the switch head 1, and the other end extends into the body 3.

[0024] In this embodiment, the spring 4 includes a support section 41 and a U-shaped elastic arm 42. One end of the support section 41 is bent upward to form a first vertical portion 43. The end of the first vertical portion 43 is bent and extended to form an elastic section. The elastic section has an inclined arm 44 that is inclined at an angle to the first vertical portion 43. The end of the inclined arm 44 away from the elastic section extends downward and bends to form an abutment portion 45. The other end of the support section 41 is bent downward to form a second vertical portion 46. The end of the second vertical portion 46 is connected to one end of the U-shaped elastic arm 42.

[0025] In this embodiment, the top of the body 3 is provided with a first placement edge 31 and a second placement edge 32, which together form an installation channel 33. The support section 41 is located within the installation channel 33. The ends of the first placement edge 31 and the second placement edge 32 facing the thermostat 2 are bent outward to form a snap-fit ​​portion 34. The first end of the abutment portion 45 is snapped into the snap-fit ​​portion 34, and the end away from the snap-fit ​​portion 34 is provided with a hollow installation groove 35. The U-shaped elastic arm 42 is located within the installation groove 35. The bottom of the installation groove 35 is coated with glue, which is used to fix the spring 4 and the body.

[0026] In this embodiment, a mounting base 12 is provided with an upward protrusion at the middle position of the switch head 1, and the thermostat 2 is located inside the mounting base 12.

[0027] In this embodiment, the spring 4 is made of iron wire.

[0028] Specifically, this application utilizes the precise cooperation between the switch head 1 and the spring piece 4 fixed within the body 3 to divide the rotation angle into multiple stages, allowing users to experience distinct tactile feedback when rotating the switch. Specifically, within a certain angle range, users not only feel a tactile difference but also hear a "click, click" sound similar to a spring, greatly enhancing the user experience during adjustment.

[0029] The rotation angle can be adjusted in segments by the outer gear ring 11 on the top of the switch head 1 cooperating with the spring piece 4 fixed in the body 3, making the temperature adjustment more precise. The tactile and auditory feedback generated during rotation (such as "click, click") allows the user to clearly perceive each gear change, improving the intuitiveness and satisfaction of use.

[0030] The outer gear ring 11 inside the switch head 1 ensures a perfect fit with the spring 4 during assembly. In actual use, when the user rotates the switch head 1, the spring 4 bounces within the outer gear ring 11, producing a "click, click" sound. The movement of the spring 4 also provides slight vibration feedback to the user's hand, creating a distinct tactile feedback experience and significantly improving the user's operating experience.

[0031] This application utilizes a simple mechanical structure, namely the outer gear ring 11 and the spring 4, to achieve complex temperature regulation functions. It is not only low in cost, but also easy to maintain and has a long service life.

[0032] Compared to devices with built-in tactile feedback (such as timer switches), this design is lower in cost, easier to maintain, and has a longer service life.

[0033] The structural design of this application aims to provide a more intuitive and precise temperature control method while ensuring the product's economy and durability. Through improvements to existing technology, not only are the problems of traditional stepless rotary switches resolved, but the user experience is further optimized, meeting the market's demand for high-quality temperature control equipment.

[0034] The structure of this application can be widely applied to household appliance products.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
