[0001] The utility model relates to the technical field of battery ovens, and particularly relates to an oven with a safety mechanism. Background Art
[0002] With the rapid development of the lithium battery industry, lithium batteries are widely used, and their performance is crucial. Moisture has a great impact on the performance of lithium batteries. During the production process of lithium batteries, the water content of the batteries must be strictly controlled. The positive and negative electrode materials, electrolyte, separator, etc. inside the lithium batteries are all prone to absorbing moisture in the air. During the production process of the batteries, the processes before baking will all absorb moisture, and the moisture absorbed by the batteries must be baked out during the baking process. The function of the vacuum oven is to volatilize the moisture inside the lithium batteries. When the vacuum oven is working, it is necessary to heat and evacuate the inner cavity. If a staff member is accidentally locked inside the vacuum oven at this time, it will lead to a safety accident. Content of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the utility model provides an oven with a safety mechanism, aiming to solve the problem that a safety accident will occur if a staff member is accidentally locked inside the vacuum oven.
[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An oven main body;
[0007] A safety mechanism, comprising: a first safety device, and the first safety device comprises: a safety box, a fixed seat, a contact switch, a swinging member, a tension spring, a pull rope, a wheel shaft and a fixing member. The safety box and the fixed seat are respectively fixed on the upper and lower parts of the side wall of the oven main body; the contact switch is installed in the safety box, and the contact switch is used for communicating with the control center of the oven; the swinging member is fixed in the safety box through a rotating shaft, and a first through hole and a second through hole are arranged at the first end of the swinging member; one end of the tension spring is fixed to the fixing member, and the other end of the tension spring is connected with the swinging member through the first through hole; the pull rope bypasses the wheel shaft, and one end of the pull rope is connected with the fixed seat, and the other end of the pull rope is connected with the swinging member through the second through hole; the second end of the swinging member is used for contacting the contact of the contact switch under the action of the tension spring, and the second end of the swinging member overcomes the acting force of the tension spring under the action of the pull rope, so as to release the contact with the contact of the contact switch.
[0008] Further, the first safety device further includes a limiting member disposed in the safety box for limiting the swinging amplitude of the swinging member under the action of the tension spring.
[0009] Further, the safety mechanism further includes a second safety device, which includes a safety window, a placement rack, and a safety hammer. A window is provided on the side wall of the oven body. The safety window is tempered glass provided in the window. The placement rack is provided on the side wall of the oven body.

Detailed implementation manners
[0023] The present utility model will be further described below in conjunction with the drawings and specific embodiments.
[0024] As Figures 1 to 5 shown, the present utility model provides an oven with a safety mechanism 2, including:
[0025] oven main body 1;
[0026] Safety mechanism 2, including: a first safety device 21, the first safety device 21 including: a safety box 211, a fixed seat 212, a contact switch 213, a swinging member 214, a tension spring 215, a pull rope 216, a wheel axle 217 and a fixing member 218. The safety box 211 and the fixed seat 212 are respectively fixed to the upper and lower parts of the side wall of the oven main body 1. The contact switch 213 is installed in the safety box 211, and the contact switch 213 is used for communicating with the control center of the oven. The swinging member 214 is fixed to the safety box 211 through a rotating shaft. A first through hole 2141 and a second through hole 2142 are provided at the first end of the swinging member 214. One end of the tension spring 215 is fixed to the fixing member 218, and the other end of the tension spring 215 is connected to the swinging member 214 through the first through hole 2141. The pull rope 216 bypasses the wheel axle 217, and one end of the pull rope 216 is connected to the fixed seat 212, and the other end of the pull rope 216 is connected to the swinging member 214 through the second through hole 2142. The second end of the swinging member 214 is used to contact the contact 2131 of the contact switch 213 under the action of the tension spring 215, and the second end of the swinging member 214 overcomes the acting force of the tension spring 215 under the action of the pull rope 216, so as to release the contact with the contact 2131 of the contact switch 213.
[0027] When the staff member is locked inside the oven main body 1, self-rescue can be carried out through the safety mechanism 2. The specific process is as follows: Since one end of the tension spring 215 is fixed to the fixing member 218 and the other end of the tension spring 215 is connected to the first end of the swinging member 214 through the first through hole 2141, when the first safety device 21 is in the normal state, the second end of the swinging member 214 contacts the contact 2131 of the contact switch 213 under the action of the tension spring 215. Since the pull rope 216 bypasses the wheel axle 217, and one end of the pull rope 216 is connected to the fixed seat 212 and the other end of the pull rope 216 is connected to the first end of the swinging member 214 through the second through hole 2142, the position of the pull rope 216 is fixed by the fixed seat 212 and the swinging member 214 to prevent the pull rope 216 from swinging and affecting the grasping of the staff member. Therefore, when the first safety device 21 is in the response state, when the pull rope 216 of the first safety device 21 is pulled by the staff member, the second end of the swinging member 214 overcomes the acting force of the tension spring 215 under the action of the pull rope 216, so as to release the contact with the contact 2131 of the contact switch 213. Since the contact switch 213 communicates with the control center of the oven, when the contact 2131 of the contact switch 213 contacts or releases the contact with the second end of the swinging member 214, different signals will be sent to the control center of the oven, so that when the second end of the swinging member 214 releases the contact with the contact 2131 of the contact switch 213, the control center of the oven controls the oven main body 1 to stop working, thereby avoiding safety accidents caused by harm to the staff member.
[0028] It should be noted that the safety box 211 includes a bottom cover and a top cover. The bottom cover and the top cover are fixedly connected to form an installation cavity. The contact switch 213, the swing member 214, the tension spring 215, the wheel axle 217, and the fixing member 218 are all installed in the installation cavity.
[0029] As Figure 4 shown, in some embodiments, the first safety device 21 further includes: a limiting member 219. The limiting member 219 is disposed in the safety box 211 and is used to limit the swing amplitude of the swing member 214 under the action of the tension spring 215.
[0030] By limiting the swing amplitude of the swing member 214 under the action of the tension spring 215 through the limiting member 219, it is possible to prevent the swing amplitude of the swing member 214 from being too large under the action of the tension spring 215 and damaging the contact 2131 of the contact switch 213.
[0031] As Figure 1 and Figure 2 shown, in some embodiments, the safety mechanism 2 further includes: the second safety device 22 includes a safety window 221, a placement rack 222, and a safety hammer 223. A window is provided on the side wall of the oven main body 1. The safety window 221 is tempered glass provided in the window. The placement rack 222 is disposed on the side wall of the oven main body 1. The safety hammer 223 is placed on the placement rack 222. The safety hammer 223 is used to break the tempered glass so that the oven main body 1 cannot achieve a vacuum.
[0032] When the staff is trapped inside the oven main body 1, they can perform self - rescue through the second safety device 22. The specific process is as follows: The staff picks up the safety hammer 223 placed on the placement rack 222, and then uses the safety hammer 223 to break the tempered glass of the safety window 221, making it impossible for the oven main body 1 to achieve a vacuum, thereby preventing the staff from suffering from hypoxia due to staying inside the oven main body 1 for a long time.
[0033] As Figure 1 shown, in some embodiments, the oven having the safety mechanism 2 further includes: a lighting lamp 23. The lighting lamp 23 is disposed on the side wall of the oven main body 1 and is used to illuminate the inside of the oven main body 1.
[0034] In order to facilitate the staff to clearly see the position of the safety mechanism 2, that is, the position of the pull rope 216 of the first safety device 21 or the safety hammer 223 and the safety window 221 of the second safety device 22, the lighting lamp 23 is provided on the side wall of the inner wall of the oven main body 1 to illuminate the inside of the oven main body 1.
[0035] As Figure 1 and Figure 2 shown, in some embodiments, the oven main body 1 is provided with two heating chambers 11, and there are two safety mechanisms 2. The two safety mechanisms 2 are respectively disposed on the side walls of the two heating chambers 11.
[0036] As Figure 1 shown in Figure 2 FIG. 6, in some embodiments, the oven with the safety mechanism 2 further includes an alarm device 24, and the alarm device 24 is disposed on the top of the oven main body 1.
[0037] When the control center of the oven detects that the second end of the swing member 214 is disengaged from the contact point 2131 of the contact switch 213, the control center controls the oven to stop working, and at the same time sends a signal to the alarm device 24 to control the alarm device 24 to emit an alarm, so as to timely notify the staff outside the oven to control the opening of the oven and rescue the trapped staff.
[0038] Specifically, the alarm device 24 is a buzzer and / or an alarm lamp.
[0039] In some embodiments, the alarm device 24 is a buzzer. When the control center of the oven detects that the second end of the swing member 214 is disengaged from the contact point 2131 of the contact switch 213, the control center controls the oven to stop working, and at the same time sends a signal to the buzzer to control the buzzer to emit a beep, so as to timely notify the staff outside the oven to control the opening of the oven and rescue the trapped staff.
[0040] In other embodiments, the alarm device 24 is an alarm lamp. When the control center of the oven detects that the second end of the swing member 214 is disengaged from the contact point 2131 of the contact switch 213, the control center controls the oven to stop working, and at the same time sends a signal to the alarm lamp to control the alarm lamp to emit light, so as to timely notify the staff outside the oven to control the opening of the oven and rescue the trapped staff.
[0041] In still other embodiments, the alarm device 24 is a combination of a buzzer and an alarm lamp. The buzzer can be built into the alarm lamp. When the control center of the oven detects that the second end of the swing member 214 is disengaged from the contact point 2131 of the contact switch 213, the control center controls the oven to stop working, and at the same time sends a signal to the buzzer and the alarm lamp to control the alarm lamp to emit light and the buzzer to emit a beep, so as to timely notify the staff outside the oven to control the opening of the oven and rescue the trapped staff.
[0042] The above are only preferred embodiments of the present invention, and do not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
