Description

Technical Field

[0001] This invention belongs to the field of heater technology, specifically a heater. Background Technology

[0002] A heater is an electrical appliance that uses electrical energy to achieve a heating effect. It has high heating power, is widely used, adopts intelligent control mode, has high temperature control accuracy, can be networked with computers, has a wide range of applications, long life, and high reliability. The core principle of a heater is energy conversion, the most common of which is the conversion of electrical energy into heat energy.

[0003] Existing heaters used on vacuum pumps typically involve simply connecting the power cord to the heater. During operation, the vacuum pump vibrates, causing the power cord to loosen and resulting in poor contact. Additionally, when not in use, the heater's plug is exposed, making it easy for dust to enter and water droplets to splash onto it, leading to oxidation and corrosion.

[0004] In summary, the present invention provides a heater to solve the above-mentioned problems. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention provides a heater to solve the problems in the prior art.

[0006] A heater includes a support unit and a heating unit, wherein the support unit includes a housing, the top of the housing has a vertically formed exhaust outlet and a general exhaust outlet, the bottom of the housing has a vertically formed exhaust inlet, and a compressed gas interface is also formed on one side of the housing;

[0007] The heating unit includes a heating element, a protective element, and fasteners. The heating element includes an annular plug located on one side of the housing. The conductor portion inside the annular plug communicates with the interior of the housing. The annular plug has a first groove and a second groove symmetrically and horizontally formed inside. The protective element includes a baffle located inside the annular plug. The conductor portion of the annular plug horizontally penetrates the baffle. The fasteners include a locking block located inside the second groove.

[0008] Preferably, an instrument is fixedly connected to the top of the housing, and the instrument is located on the general exhaust side.

[0009] Preferably, the heating element further includes a heating tube disposed inside the housing, the heating tube being bent and arranged on the inner wall of the housing, and the heating tube being fixedly connected to the inner wall of the housing, with both ends of the heating tube being connected to a conductor inside the annular plug.

[0010] Preferably, the protective component further includes a limiting rod located within the first slide groove, with both ends of the limiting rod fixedly connected to the inner wall of the first slide groove, a limiting block provided on the limiting rod, the limiting block being slidably connected to the limiting rod, and the limiting block being fixedly connected to the baffle.

[0011] Preferably, a first elastic element is sleeved on one end of the limiting rod, one end of the first elastic element is fixedly connected to the inner wall of the first slide groove, and the other end of the first elastic element is fixedly connected to the limiting block, wherein the first elastic element is preferably a spring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention uses a baffle in the protective component. When the heater is not in use, the baffle can automatically pop out to seal the inside of the ring plug, preventing dust from falling into the ring plug and preventing water from splashing into the ring plug. This avoids poor contact between the power cord plug and the ring plug or oxidation and corrosion of the ring plug, thereby ensuring the stable operation of the heater.

[0015] 2.

[0024] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0025] This invention provides a heater, comprising:

[0026] The supporting unit 1 for supporting the object includes a housing 11 for protecting the heating tube 214. The top of the housing 11 is vertically provided with an exhaust outlet 12 for gas discharge and a general exhaust outlet 13. The bottom of the housing 11 is vertically provided with an exhaust inlet 14 for gas to enter. The side of the housing 11 is also provided with a compressed gas interface 15 for gas to enter.

[0027] The heating unit 2 for heating includes a heating element 21 for heating the inside of the outer shell 11, a protective element 22 for protecting the annular plug 211, and a fastener 23 for securing the wire. The heating element 21 includes an annular plug 211 located on one side of the outer shell 11 for heating the heating tube 214. The conductor portion inside the annular plug 211 communicates with the inside of the outer shell 11. The annular plug 211 has symmetrically horizontally formed first grooves 212 for accommodating the limiting block 223 and second grooves 213 for accommodating the locking block 231. The protective element 22 includes a baffle 221 located inside the annular plug 211 for protecting the conductor portion of the annular plug 211. The conductor portion of the annular plug 211 horizontally passes through the baffle 221. The fastener 23 includes a locking block 231 located inside the second groove 213 for securing the wire.

[0028] An instrument 16 for monitoring the temperature inside the housing 11 is fixedly connected to the top of the housing 11, and the instrument 16 is located on the side of the general exhaust 13.

[0029] The heating element 21 also includes a heating tube 214 located inside the outer shell 11 for heating the interior of the outer shell 11. The heating tube 214 is bent and arranged on the inner wall of the outer shell 11 and is fixedly connected to the inner wall of the outer shell 11. Both ends of the heating tube 214 are respectively connected to the conductor inside the annular plug 211.

[0030] The protective component 22 also includes a limiting rod 222 located in the first slide groove 212 to limit the limiting block 223. The two ends of the limiting rod 222 are fixedly connected to the inner wall of the first slide groove 212. The limiting rod 222 is provided with a limiting block 223 to facilitate the movement of the baffle 221. The limiting block 223 is slidably connected to the limiting rod 222 and fixedly connected to the baffle 221.

[0031] One end of the limiting rod 222 is fitted with a first elastic element 224 for pushing the limiting block 223 to move. One end of the first elastic element 224 is fixedly connected to the inner wall of the first slide groove 212, and the other end of the first elastic element 224 is fixedly connected to the limiting block 223.

[0032] One end of the locking block 231 is provided with a pull rod 232 for moving the locking block 231. One end of the pull rod 232 passes horizontally through the annular plug 211. One end of the pull rod 232 is sleeved with a second elastic element 233 for pushing the locking block 231 to move. One end of the second elastic element 233 is fixedly connected to the inner wall of the second slide groove 213, and the other end of the second elastic element 233 is fixedly connected to the locking block 231.

[0033] Example 1:

[0034] like Figure 1-7 As shown, the present invention provides a heater. In this embodiment, when the heater is needed, one end of the power cord plug is inserted into the ring plug 211. The power cord plug first contacts the baffle 221, and then the power cord plug is inserted into the ring plug 211. The power cord plug will push the baffle 221 to move. The baffle 221 pushes the limiting block 223 to move along the limiting rod 222 in the first sliding groove 212. When the limiting block 223 moves, it squeezes the first elastic member 224, causing the first elastic member 224 to undergo elastic deformation under force.

[0035] Furthermore, when the power cord plug is inserted into the ring plug 211 to a certain extent, by pulling the lever 232, the lever 232 causes the locking block 231 to move into the second slide groove 213. Due to the limitation of the second elastic member 233 by the inner wall of the second slide groove 213, the locking block 231 pushes the second elastic member 233 to undergo elastic deformation. When the locking block 231 is completely moved into the second slide groove 213, the locking block 231 releases the restriction on the baffle 221, and the power cord plug is completely inserted into the ring plug 211.

[0036] Furthermore, by releasing the lever 232, the second elastic element 233 is released from its stress and elastically resets, pushing the locking block 231 to move until the locking block 231 is tightly fitted to one side of the power cord plug. This increases the friction between the power cord plug and the ring plug 211, making the power cord plug less prone to loosening and better able to provide power to the heating element 214.

[0037] Furthermore, after the power cord plug comes into contact with the ring plug, power is transmitted to the heating tube 214, and the heating tube 214 emits heat.

[0038] Example 2:

[0039] Reference Figures 5-7 This embodiment differs from the first embodiment in that: after the heater is used up, by pulling the lever 232, the lever 232 moves the locking block 231 into the second slide groove 213. At the same time, the locking block 231 pushes the second elastic member 233 to undergo elastic deformation. When the locking block 231 is fully moved into the second slide groove 213, the friction between the power cord plug and the ring plug 211 decreases. By pulling the power cord plug out of the ring plug 211, the first elastic member 224 is relieved of its force. The first elastic member 224 pushes the limiting block 223 to move along the limiting rod 222 in the first slide groove 212. The limiting block 223 moves the baffle 221 to one end of the ring plug 211, sealing the inside of the ring plug 211, thereby preventing dust from falling into the ring plug 211 and preventing water from splashing into the ring plug 211. This avoids poor contact between the power cord plug and the ring plug 211 or oxidation and corrosion of the ring plug 211, thus ensuring the stable operation of the heater.
