Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil fume purification, and particularly relates to an oil fume purifier capable of automatically releasing high-voltage static electricity when a door is opened. BACKGROUND

[0002] As a high-efficiency kitchen oil fume treatment device, the high-voltage static electricity oil fume purifier is widely used in the catering industry and industrial fields. The working principle thereof is to make oil fume particles charged through a high-voltage static field, and to collect the oil fume particles under the action of the electric field, so as to realize the purification of the oil fume. Generally, the working voltage of such a device is relatively high, and is commonly between DC 12000V and 20000V, so as to ensure that the electric field has sufficient adsorption capacity.

[0003] During the operation of the device, the power supply continuously applies a high-voltage voltage to the anode of the electric field to form a strong static electric field. However, after the power supply is turned off, a large amount of electric charges are temporarily stored due to the capacitive characteristics of the electric field structure (such as metal plates, electrodes, etc.). If the discharging is not timely and complete, the residual electric charges will form high-voltage static electricity, which poses a significant safety hazard. When the maintenance personnel open the maintenance door of the purifier for cleaning or maintenance, if the personnel accidentally touch the charged components, the personnel may be electrocuted. A slight electric shock can cause discomfort, and a strong electric shock can cause the personnel to lose balance due to a sudden reaction, especially in a suspended operation environment, which is more likely to cause a falling accident and cause personal injury.

[0004] At present, most high-voltage static electricity oil fume purifiers on the market are not equipped with an effective automatic discharging mechanism, and generally rely on manual discharging or natural discharging, which has problems such as incomplete discharging, inconvenient operation, and low reliability. Therefore, there is an urgent need for a safety device capable of automatically, quickly and completely releasing residual electric charges of the electric field when the maintenance door is opened, so as to ensure the safety of the maintenance personnel.

Therefore, the invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0033] Example 1 Reference Figure 1 , Figure 2 , Figure 3 , Figure 6This is the first embodiment of the present invention. This embodiment provides an oil fume purifier that automatically releases high voltage static electricity when the door is opened, which can realize the automatic discharge of residual electricity on the electric field. It includes: a purifier body 100, a purifier maintenance door 101 and a purifier power box door 102 provided on one side of the purifier body 100, the purifier maintenance door 101 is hinged to the purifier body 100, the purifier power box door 102 is hinged to the purifier maintenance door 101, a conductive element 103 is fixedly provided on the inner side of the purifier maintenance door 101, an insulator is sleeved on the conductive element 103, the conductive element 103 is in a positional insulation state with the purifier maintenance door 101 through the insulator, and the conductive element 103 outside the insulator is connected to a high voltage power supply. Reference Figure 6 The purifier body 100 contains an electric field component 104. One end of the electric field component 104 includes a high-voltage electrode mounting plate 104b and a low-voltage electrode mounting plate 104c, both of which are anodes. The electric field component 104 also includes a housing 104a, which is grounded during installation and serves as the cathode. The high-voltage electrode mounting plate 104b and the low-voltage electrode mounting plate 104c are mounted at both ends of the housing 104a via insulators. The electric field discharge electrode and the anode plate are mounted on the high-voltage and low-voltage electrode mounting plates, and the cathode and anode are completely insulated. A conductive spring 105 is provided at one end of the electric field component 104. Reference Figure 6 An electric field discharge unit 200 is provided inside the main body 100 of the purifier. The electric field discharge unit 200 is located at one end of the electric field of the electric field component 104 and between the high voltage electrode mounting plate 104b and the low voltage electrode mounting plate 104c.

[0034] During operation, when the purifier maintenance door 101 is closed, the conductive component 103 inside the insulator comes into contact with the conductive spring 105 on the electric field, thus energizing the electric field and allowing the fume purifier to work normally. When the purifier maintenance door 101 is opened, the residual charge on the electric field is automatically discharged through the electric field discharge unit 200 to ensure the safety of maintenance personnel.

[0035] Example 2 Reference Figures 3 to 9 This is the second embodiment of the present invention. Based on the previous embodiment, the electric field discharge unit 200 includes a guide post assembly and a conductive plate assembly.

[0036] Reference Figure 8 The guide post assembly includes a base plate 201, a travel guide post 202, and a limit guide post 203. The base plate 201 is fixedly mounted on the end face of the housing 104a, and the travel guide post 202 and the limit guide post 203 are welded and fixed on the base plate 201.

[0037] Reference Figure 8 , Figure 9The guide plate assembly includes a conductive plate 205, a travel guide sleeve 206, and a limiting guide sleeve 207. The travel guide sleeve 206 and the limiting guide sleeve 207 are welded and fixed on the guide plate 205. The travel guide sleeve 206 is fitted into the travel guide post 202, and the limiting guide sleeve 207 is fitted into the limiting guide post 203. Then, a retaining spring 208 is installed in the slot at one end of the limiting guide post 203 to prevent the conductive plate assembly from falling off.

[0038] Reference Figure 8 A support spring 204 is sleeved on the travel guide column 202. The two ends of the support spring 204 are respectively set on the base plate 201 and the guide plate 205. In the natural state of the support spring 204, the conductive plate 205 simultaneously abuts against the high voltage electrode mounting plate 104b and the low voltage electrode mounting plate 104c under the elastic support of the support spring 204.

[0039] In use, the initial state of the electric field discharge unit 200 in the electric field is as follows: the base plate 201 is fixed on the end face of the electric field housing 104a, which is grounded at this time. The conductive plate 205 is in contact with the high and low voltage electrode mounting plates of the electric field under the elastic support of the support spring 204. At this time, the anode and cathode of the electric field are in a short circuit state and safely grounded. The residual charge in the electric field can be automatically discharged to ensure the safety of maintenance personnel. Since the conductive plate assembly is supported by a spring, when the conductive plate assembly is subjected to force in the direction of the base plate 201, the support spring 204 is compressed, and the conductive plate 205 moves away from the high and low voltage electrode mounting plates of the electric field and is greater than the creepage distance. Then the cathode and anode of the electric field are disconnected and can work normally.

[0040] The electric field operates in the air purifier as follows: When the air purifier maintenance door 101 is closed, the conductive element 103 inside the insulator contacts the conductive spring 105 on the electric field, thus energizing the electric field; when the air purifier maintenance door 101 is opened, the conductive element 103 inside the insulator separates from the conductive spring 105 on the electric field, thus de-energizing the electric field. Simultaneously, when the air purifier maintenance door 101 is closed, one end of the travel guide sleeve 206 contacts the inner surface of the air purifier maintenance door 101, pushing the entire conductive plate assembly to fully compress with the support spring 204 and separate from the high and low voltage electrode mounting plates of the electric field, thus enabling normal operation of the electric field; when the maintenance door is opened, the support spring 204 supports the conductive plate assembly to contact the high and low voltage electrode mounting plates of the electric field, immediately achieving the purpose of electric field discharge.

[0041] It is worth noting that: all standard parts used in this application can be purchased from the market, and irregular parts can be customized according to the description and drawings. The machinery, parts and equipment all adopt conventional models in the prior art.

[0042] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
