Description

Technical Field

[0001] The utility model relates to the technical field of oven temperature control, in particular to an oven lamp temperature control device. Background Art

[0002] The main principle of oven temperature control is to sense the temperature inside the oven through a temperature sensing element, convert the signal into an electrical signal, and then send it to the control switch for processing, thereby adjusting the oven temperature.

[0003] The oven temperature is raised by the oven light. The temperature sensing element is set at the oven light position to sense the temperature most quickly, but installing the temperature sensing element here will hinder the installation of the oven bulb. Utility Model Content

[0004] The utility model aims to provide an oven lamp temperature control device to solve the problem in the background art that the temperature sensing element is arranged at the oven lamp position for the fastest temperature sensing, but the installation of the temperature sensing element here will hinder the installation of the oven lamp.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An oven lamp temperature control device comprises a lamp holder, a light bulb is threadedly mounted on the lamp holder, a metal conical spiral piece is arranged on the mounting surface of the lamp holder located at the light bulb, one end of the metal conical spiral piece is fixedly connected to a thermal sensing needle, the thermal sensing needle is inserted into the lamp holder and connected to a signal receiver, and the other end of the metal conical spiral piece is integrally connected to a protective head.

[0007] As a further description of the above technical solution:

[0008] The lamp holder is provided with an internal thread groove.

[0009] As a further description of the above technical solution:

[0010] The internal thread groove is coaxially arranged with the metal conical spiral member.

[0011] As a further description of the above technical solution:

[0012] The protective head is in an arc-shaped curved shape.

[0013] As a further description of the above technical solution:

[0014] The protective head is located at the rear of the end of the metal conical spiral member.

[0015] As a further description of the above technical solution:

[0016] A distance is left between the metal conical spiral component and the bulb.

[0017] Compared with the prior art, the utility model provides an oven lamp temperature control device, which has the following beneficial effects:

[0018] 1. In the utility model, a metal conical spiral is installed at the end of the heat-sensing needle, so that the metal conical spiral is directly around the outside of the light bulb, and the shape of the metal conical spiral has a large contact surface with the hot air around the light bulb and does not hinder the light bulb from transferring heat out. The metal conical spiral can quickly heat up and transfer the temperature to the heat-sensing needle;

[0019] 2. In the utility model, a protective head is provided at the end of the metal conical spiral member. The protective head is arc-shaped and bent behind the end of the metal conical spiral member. This can prevent the installation and removal of the bulb from causing accidental damage due to the pointed end of the metal conical spiral member hitting the glass surface of the bulb.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-Figure 2 The utility model provides an oven lamp temperature control device, including a lamp holder 1, a light bulb 2 is threadedly installed on the lamp holder 1, a metal conical spiral part 3 is arranged on the mounting surface of the lamp holder 1 located at the light bulb 2, one end of the metal conical spiral part 3 is fixedly connected to a thermal sensing needle 4, the thermal sensing needle 4 is inserted into the lamp holder 1 and connected to a signal receiver, and the other end of the metal conical spiral part 3 is integrally connected to a protective head 5.

[0027] Specifically, Figure 2 As shown, the lamp holder 1 is provided with an internal thread groove, which is coaxially arranged with the metal conical screw member 3 to facilitate the installation of the bulb 2.

[0028] Specifically, Figure 1 and Figure 2 As shown, the protective head 5 is arc-shaped and is located at the rear of the end of the metal conical spiral 3. There is a distance between the metal conical spiral 3 and the bulb 2. When the bulb 2 is disassembled and removed, even if the protective head 5 contacts the glass surface, the contact is in an arc shape and will not damage the glass surface.

[0029] Working principle:

[0030] When installing the bulb 2 on the lamp holder 1, since the end of the metal conical spiral 3 is designed with a protective head 5, the protective head 5 is behind the outermost circle of the metal conical spiral 3, and the protective head 5 is arc-shaped, so when the bulb 2 is installed and removed, the end of the metal conical spiral 3 will not scratch the glass surface of the bulb 2. After the bulb 2 heats up, the metal conical spiral 3 is closest to the bulb 2. In addition, the contact area between the metal conical spiral 3 and the hot air is large and does not block heat radiation. The metal conical spiral 3 quickly heats up and transfers the temperature to the thermal sensing needle 4, thereby realizing the transmission of the temperature control signal.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
