[0001] This utility model relates to the field of heater technology, and more specifically, to a gas heater for intelligent temperature control. Background Technology

[0002] A gas heater is an electric heater used to heat gas. It has a gas channel inside the heater. When the gas flows through the gas channel, it is heated by a heating wire. For example, during endoscopic surgery, carbon dioxide gas needs to be delivered into the human body through an insufflator. In order to keep the carbon dioxide delivered into the human body at the same temperature as the body, the carbon dioxide gas needs to be heated during delivery.

[0003] A search revealed that patent publication number CN220728526U discloses a gas heater, including a housing, a mounting plate, and a heating rod. The interior of the housing is a heating chamber, and an inlet pipe and an outlet pipe are located near both ends of the housing, both communicating with the heating chamber. The heating rod is fixedly mounted on the mounting plate and located within the heating chamber, and the heating rod is arranged in a spiral shape. The mounting plate is located at the opening of the housing. This application facilitates the heating of the conveyed gas. During the development of this utility model, the inventors discovered the following problems with the existing technology:

[0004] When the device is in use, the connection between the mounting plate and the inner wall thread at the opening of the housing is achieved by screwing the threads on the mounting plate. However, the mounting plate has a connection circuit that connects to both ends of the heating rod. When disassembling the mounting plate and the heating rod on the mounting plate, the mounting plate needs to be rotated. At this time, the connection circuit that connects the two ends of the heating rod through the mounting plate will become tangled, causing some inconvenience. In addition, the threaded connection between the housing and the mounting plate will wear down over time, which will affect the stability of the connection between the mounting plate and the housing.

[0005] Therefore, a gas heater for intelligent temperature control is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a gas heater for intelligent temperature control to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gas heater for intelligent temperature control, comprising a heater housing, a placement seat fixedly connected to the inner wall of one end of the heater housing, a placement groove provided between the placement seat and the heater housing, a rubber gasket provided on the bottom wall of the placement groove, an installation plate covering one end of the heater housing, an annular insert welded to one side surface of the installation plate, the annular insert being inserted into the placement groove, a plurality of locking blocks evenly spaced on the outer wall of the annular insert, a plurality of locking grooves evenly spaced on the outer wall of the heater housing engaging with the locking blocks, and a locking assembly provided between the heater housing and the outer wall of the installation plate.

[0008] Preferably, the locking assembly includes a first connecting seat, a rod, a stop, a compression spring, and a second connecting seat. The first connecting seat is fixedly connected to the outer wall of the mounting plate, and a connecting hole is provided on the first connecting seat. The second connecting seat is welded to the outer wall of the top of the heater housing. The rod is movably inserted through the second connecting seat. The stop is fixedly connected to the outer side of the rod. A compression spring is sleeved on the outer side of the rod and located between the stop and the second connecting seat.

[0009] Preferably, the bottom end of the insertion rod is fixedly connected to an adjustment knob for pulling the insertion rod, and the outer side of the adjustment knob is provided with rough texture to increase the friction between the hand and the adjustment knob.

[0010] Preferably, the surface of the mounting plate is provided with a rotating handle for adjusting the rotation of the mounting plate.

[0011] Preferably, a heating rod is mounted on the mounting plate, and the heating rod is disposed inside the heater housing.

[0012] Preferably, the heater housing surface is provided with an air inlet pipe that is connected and communicates with the heater housing, and the heater housing surface and located on one side of the air inlet pipe are provided with an air outlet pipe that is connected and communicates with the heater housing.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with the prior art, the connection between the mounting plate and the heating rod installed on it is achieved by the engagement of the annular plug fixed to one side surface of the mounting plate with the placement groove.

[0021] Example 1

[0022] As attached Figures 1 to 4The gas heater for intelligent temperature control shown includes a heater housing 1. A placement seat 2 is fixedly connected to the inner wall of one end of the heater housing 1. A placement groove 3 is provided between the placement seat 2 and the heater housing 1. A rubber gasket 4 is provided on the bottom wall of the placement groove 3. An installation plate 8 is covered at one end of the heater housing 1. An annular insert 7 is welded to one side surface of the installation plate 8. The annular insert 7 is inserted into the placement groove 3. A plurality of locking blocks 6 are provided at equal intervals on the outer wall of the annular insert 7. A plurality of locking grooves 5 are provided at equal intervals on the outer wall of the heater housing 1 to engage with the locking blocks 6. A locking component is provided between the heater housing 1 and the outer wall of the installation plate 8.

[0023] In use, the device can first be rotated counterclockwise by turning the handle 15 to rotate the mounting plate 8. Then, the rotating mounting plate 8 drives the annular insert 7 and the locking block 6 set on the annular insert 7 to rotate. Subsequently, the rotating locking block 6 rotates in the locking groove 5 opened on the outer wall of the heater housing 1. Then, the locking block 6 is pulled by turning the handle 15 to remove the locking block 6 from the locking groove 5, thereby releasing the limiting connection between the mounting plate 8 and the heating rod 16 set on the mounting plate 8 and the heater housing 1, and thus removing the heating rod 16 from the heater housing 1, which facilitates the subsequent maintenance of the heating rod 16.

[0024] Example 2

[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, the locking assembly includes a first connecting seat 9, a rod 10, a stop block 11, a compression spring 12, and a second connecting seat 13. The first connecting seat 9 is fixedly connected to the outer wall of the mounting plate 8, and a connecting hole is provided on the first connecting seat 9. The second connecting seat 13 is welded to the outer wall of the top of the heater housing 1. The rod 10 is movably inserted through the second connecting seat 13. The stop block 11 is fixedly connected to the outer side of the rod 10. The compression spring 12 is sleeved on the outer side of the rod 10 and located between the stop block 11 and the second connecting seat 13. An adjustment knob 14 for pulling the rod 10 is fixedly connected to the bottom end of the rod 10. The outer side of the adjustment knob 14 is provided with rough texture to increase the friction between the hand and the adjustment knob 14. Furthermore, when the device is in use, the rod 10 can be pulled by adjusting the knob 14 first, and then the rod 10 can be moved away from the first connecting seat 9, thereby releasing the locking connection between the heater housing 1 and the mounting plate 8, which facilitates the disassembly and maintenance of the mounting plate 8 and the heating rod 16 provided on the mounting plate 8.

[0027] In a preferred embodiment, the surface of the mounting plate 8 is provided with a rotating handle 15 for rotating and adjusting the mounting plate 8. A heating rod 16 is mounted on the mounting plate 8 and is disposed inside the heater housing 1. An air inlet pipe 17 connected to and communicating with the heater housing 1 is provided on the surface of the heater housing 1 and an air outlet pipe 18 connected to and communicating with the heater housing 1 is provided on the surface of the heater housing 1 and on one side of the air inlet pipe 17. Further, the power supply to the heating rod 16 is first disconnected so that the heating rod 16 can heat the gas entering the heater housing 1. Then, the gas to be heated is introduced through the air inlet pipe 17. Then, the heated gas entering the heater housing 1 is heated by the heated heating rod 16. Finally, the heated gas is discharged from the heater housing 1 through the air outlet pipe 18 for use.

[0028] The working process of this utility model is as follows: First, the gas to be heated can be introduced into the heater housing 1, and then the power of the heating rod 16 is turned on. The gas entering the heater housing 1 is heated by the heating rod 16, and then the heated gas is discharged from the heater housing 1 through the gas outlet pipe 18.

[0029] When the heating rod 16 needs maintenance, one hand can pull the insertion rod 10 through the adjustment knob 14. The insertion rod 10 then moves away from the first connecting seat 9, thereby releasing the locking connection between the heater housing 1 and the mounting plate 8. Then, the other hand can rotate the mounting plate 8 counterclockwise through the rotating handle 15. The rotating mounting plate 8 drives the annular insertion block 7 and the locking block 6 set on the annular insertion block 7 to rotate. The rotating locking block 6 then rotates in the slot 5 opened on the outer wall of the heater housing 1. Then, by rotating the handle 15, the locking block 6 is pulled to remove the locking block 6 from the slot 5, thereby releasing the limiting connection between the mounting plate 8 and the heating rod 16 set on the mounting plate 8 and the heater housing 1, and thus removing the heating rod 16 from the heater housing. The heating rod 16 is disassembled from the inner wall to facilitate subsequent maintenance. After the maintenance of the heating rod 16 is completed, the annular insert 7 can be inserted into the placement slot 3 again, and the locking block 6 is aligned with the slot 5 opened on the side wall of the heater housing 1. Then, by turning the handle 15 clockwise, the mounting plate 8 is rotated so that the locking block 6 on the outer side of the annular insert 7 can be inserted into the end of the slot 5 opened on the outer side wall of the heater housing 1. Finally, the adjustment knob 14 is released. At this time, the compression spring 12 compresses the stop block 11. The compressed stop block 11 drives the insert rod 10 to approach the limiting hole opened on the surface of the first connecting seat 9 and insert it into the limiting hole, thus completing the locking connection between the heater housing 1 and the mounting plate 8. The above is the working principle of this intelligent temperature control gas heater.
