[0002] Electric heating drying ovens are widely used in laboratories, industrial production, and food processing. In the production of cigarette adhesive, electric heating drying ovens are commonly used to determine the evaporation residue of the cigarette adhesive.

[0003] Utility model patent CN213578462U discloses an electric heating drying oven for testing cigarette adhesive. It includes a drying oven body with shelves, and a shelf height adjustment mechanism within the drying oven body. The shelf height adjustment mechanism includes a shelf support platform and screws vertically positioned at the four corners of the shelf support platform. The upper and lower ends of the screws are mounted on the drying oven body via bearings. Each screw is fitted with a nut. This device reduces height deviation caused by human error. The nut-screw structure improves the adjustment accuracy of rising or falling. A belt drive mechanism ensures transmission stability and accuracy while reducing transmission noise. However, this drying oven directly draws outside air into the oven during use. During this process, dust and other particles in the air also enter the drying oven. Dust and other contaminants can affect the determination of the evaporation residue of cigarette adhesive, thus affecting the accuracy of the cigarette adhesive test. Utility Model Content

[0004] The purpose of this invention is to provide an electric heating drying oven for testing cigarette adhesive, which prevents dust from entering the drying oven during the drying process and thus affecting the test results.

[0024] Please see Figure 1-3 This utility model provides an electric heating drying oven for testing cigarette adhesive, comprising:

[0025] Box 1, the box 1 is provided with a fixed partition to divide its internal space into a drying chamber 101 and an equipment chamber 102. The drying chamber 101 is located above the equipment chamber 102. The cigarette adhesive is dried in the drying chamber 101. The fixed partition 106 is provided with ventilation holes 103 so that the drying hot air can enter the drying chamber 101.

[0026] A fan 2 is installed in the equipment compartment 102. The air outlet of the fan 2 faces the ventilation hole 103 and an electric heating component 201 is installed at the air outlet. The electric heating component 201 is used to heat the air generated by the fan 2 to form hot air for drying cigarette adhesive. An air inlet hood 202 is installed at the air inlet of the fan 2. The air inlet hood 202 is connected to the housing 1 and a filter module 203 is installed at the port of the air inlet hood 202. The filter module 203 can be made of a combination of non-woven filter cotton, activated carbon composite layer, glass fiber and other filter materials. The filter module 203 filters the outside air and prevents dust from entering the drying compartment 101. The side wall of the housing 1 is also provided with a cleaning component for cleaning the surface of the filter module 203.

[0027] The drying chamber 101 is hinged to a door 104, which has a glass observation window 207 for real-time observation of the drying status of the cigarette adhesive. A latch 105 is also provided on one side of the door 104, which can lock with the side wall of the drying chamber 101.

[0028] In some embodiments, the cleaning assembly includes a mounting bracket 204, a lifting cylinder 205, and a scraper 206. The mounting bracket 204 is positioned above the port of the air inlet hood 202, and the lifting cylinder 205 is mounted on the mounting bracket 204. The extension end of the lifting cylinder 205 faces downward, and the scraper 206 is mounted on the extension end. A cleaning cotton is mounted on one side of the scraper 206, and the cleaning cotton is in contact with the surface of the filter module 203. By moving the scraper 206 driven by the lifting cylinder 205, dust on the end face of the filter module 203 can be scraped off, thus preventing clogging of the filter module 203.

[0029] To expel hot air from the drying chamber 101, an air outlet duct 3 is installed at the rear of the drying chamber 101 to facilitate air circulation. To prevent dust from entering the drying chamber 101 from the air outlet duct 3, a protective mesh 301 is installed inside the air outlet duct 3, and a check valve 302 is installed at the rear end of the housing 1 at the location of the air outlet duct 3, thus achieving the effect of allowing airflow only out and not in. Multiple sets of support strips 303 are provided on both sides of the inner wall of the drying chamber 101, and a shelf 107 is provided on the support strips 303. The shelf 107 has a mesh structure, which facilitates the flow of hot air when multiple layers are placed.

[0030] Preferably, the filter module 203 is provided with a sealing ring on the outside, which contacts the inner wall of the air inlet cover 202. The filter module 203 is connected to the housing 1 by bolts, thereby facilitating the disassembly and replacement of the filter module 203.

[0031] In some embodiments, the electric heating assembly 201 includes an air guide shroud 201b and electric heating tubes 201a. The air guide shroud 201b is connected to the air outlet of the fan 2, and its upper port is connected to the fixed partition 106, covering the ventilation holes 103. The electric heating tubes 201a are spaced apart within the air guide shroud 201b, so that all the airflow generated by the fan 2 can enter the air guide shroud 201b and be heated by the electric heating tubes 201a to form a hot airflow that flows into the drying chamber 101. Furthermore, a touch panel is provided at the bottom of the front end of the housing 1 to control the fan 2, the electric heating tubes 201a, and the lifting cylinder 205.

[0032] The working principle of this utility model is as follows: When using this device, the power is turned on, and about 1g of cigarette adhesive sample is weighed using a weighing bottle. The door 104 is opened, the weighing bottle is placed on the placement plate 107, and then the door 104 is closed. The fan 2 generates wind, which is then generated by the electric heating component 201 to form hot air and delivered to the interior of the drying chamber 101 through the ventilation hole 103. The air inlet hood 202 provides air intake for the fan 2. The filter module 203 can filter the outside air to prevent dust and other impurities from entering the interior of the drying chamber 101. The air outlet pipe 3 can discharge the gas inside the drying chamber 101, and the check valve 302 can prevent outside gas from entering the interior of the drying chamber 101, keeping the interior of the drying chamber 101 in a dust-free environment and preventing dust from affecting the testing accuracy of the cigarette adhesive. The lifting cylinder 205 can drive the scraper 206 to be raised and lowered, thereby scraping off the dust at one end of the filter module 203 to prevent the filter module 203 from being blocked and to facilitate the rapid drying of the cigarette adhesive.

[0033] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides modifications and improvements to the components or layout, other uses will be apparent to those skilled in the art.
