Description

Technical Field

[0001] This utility model belongs to the field of electric heater technology, and specifically relates to a duct-type electric heater. Background Technology

[0002] The duct-type electric heater consists of two parts: the main body and the control system. The heating element uses a stainless steel tube as a protective sleeve, high-temperature resistance alloy wire, and crystalline magnesium oxide powder, formed by compression. The control section uses advanced digital circuits, integrated circuit triggers, high reverse voltage thyristors, etc., to form an adjustable temperature measurement and constant temperature system, ensuring the normal operation of the electric heater.

[0003] A search revealed a duct-type electric heater with publication number CN219063766U. This heater includes a duct-type electric heater housing, an electric heating element housed inside the housing, an installation device on the side of the housing, and an auxiliary device inside the housing. This auxiliary device includes a dustproof mesh plate, an internal fixed rectangular frame, a magnetic suction plate, a magnetic plate, and an inner top anti-wear plate. The inner top anti-wear plate is fixedly connected to the inner top of the duct-type electric heater housing. By incorporating this auxiliary device, the dustproof mesh plate is connected and installed using a magnetic suction assembly with the magnetic suction plate and magnetic plate. This eliminates the need for complicated installation and removal. The dustproof assembly can be replaced without turning a knob to move the circular plate away from the annular pressure plate, making replacement convenient and improving performance during use.

[0004] In current technology, when installing a duct-type electric heater in a ventilation duct, the duct-type electric heater is fixedly connected to the ventilation duct through a mounting plate at the end face. However, the duct-type electric heater does not have an external auxiliary support structure. That is, when the bottom of the duct-type electric heater is suspended between the support surface, the stability is poor during later use. Therefore, it is necessary to design a duct-type electric heater to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a duct-type electric heater to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a duct-type electric heater, comprising a duct-type electric heater body, wherein guide cylinders are symmetrically welded to the outer wall of the duct-type electric heater body, and a support assembly is installed below the guide cylinders;

[0007] The support assembly includes a guide rod that is slidably inserted into the bottom opening of the guide cylinder, a positioning seat that is fixedly connected to the bottom end of the guide rod, a support plate that is fixedly connected to the surface of the positioning seat, a rubber seat and a spring seat that are fixedly connected to the bottom of the support plate, and a base plate that is bonded to the bottom end of the rubber seat.

[0008] Preferably, the free end of the guide rod is slidably inserted into the inside of the guide cylinder, and a positioning groove is provided on the outer wall of the guide rod.

[0009] Preferably, a locking wheel is helically inserted into the outer wall of the guide cylinder, and the insertion end of the locking wheel extends into the positioning groove.

[0010] Preferably, the bottom end of the spring seat is fixedly connected to the base plate, and the two sets of spring seats are located on both sides of the rubber seat.

[0011] Preferably, a side plate is vertically mounted on the surface of the base plate, and a bolt is helically inserted into the surface of the side plate, the bolt being located on the outer side of the positioning seat.

[0012] Preferably, a mounting base is welded to the upper surface of the duct-type electric heater body, and a top plate is fixedly connected to the top of the mounting base.

[0013] Preferably, the surface of the top plate is symmetrically provided with mounting holes, and both ends of the top plate extend to the outer wall of the duct-type electric heater body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A support assembly is installed below the guide cylinder on the outer wall of the duct-type electric heater body. After the duct-type electric heater body and the ventilation duct are connected, the guide rod is pulled down relative to the guide cylinder according to the distance between the bottom of the duct-type electric heater body and the support surface until the bottom plate is attached to the support surface. The bottom plate is then pressed and fixed using locking devices. The support assembly provides auxiliary support to the duct-type electric heater body through the support surface, resulting in good stability. Both the rubber seat and the spring seat have excellent buffering performance, filtering the duct-type electric heater body. The bolts on the side plate can also be screwed on, with the bolt insertion end extending to the outer wall of the positioning seat, achieving a rigid connection between the bottom plate and the guide rod.

[0016] 2. An assembly base is welded to the upper surface of the duct-type electric heater body. A top plate is fixedly connected to the top of the assembly base. A locking device can also be used to penetrate the top plate to install and fix the top position of the duct-type electric heater body on the support surface. Attached Figure Description
