Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mask bags, in particular to a dry-wet separation mask bag and a piston type barrier piece thereof. BACKGROUND

[0002] Common masks on the market generally mix and seal mask liquid and mask cloth in the same packaging bag, and the user can use the mask by opening the packaging bag and applying the mask cloth soaked with mask liquid to the face. However, the mask cloth is more prone to bacterial growth after being soaked with mask liquid, so more preservative ingredients need to be added, and the surface tension of the mask cloth will increase after being soaked with mask liquid for a long time, so that the elasticity and water absorption effect will be greatly reduced when used.

[0003] In the prior art, a dry-wet separation type packaging bag is generally realized by an intermittent line. The intermittent line needs to be opened by extrusion force. If the force range is small, the intermittent line is easily squeezed open during transportation. If the force range is large, it is difficult for the user to squeeze it open during use. Since the transportation process is uncontrollable and the user's strength is different, the force range of the intermittent line is difficult to determine, and needs to be improved. SUMMARY

[0004] The purpose of the present application is to provide a dry-wet separation mask bag and a piston type barrier piece thereof, in order to prevent the mask liquid from entering the mask cloth cavity when the mask bag is not used.

[0005] The dry-wet separation mask bag and the piston type barrier piece thereof provided by the present application adopt the following technical solution: a bag body is provided, the bag body is provided with a mask liquid cavity and a mask cloth cavity, and the bag body is connected with a barrier piece for controlling the on-off of the mask liquid cavity and the mask cloth cavity.

[0006] By adopting the above technical solution, the mask liquid is placed in the mask liquid cavity, and the mask cloth is placed in the mask cloth cavity. When the mask bag is not used, the mask liquid cavity and the mask cloth cavity are blocked by the barrier piece, so that the mask cloth is prevented from being soaked with mask liquid when the mask bag is affected by external force during transportation, that is, the mask cloth is prevented from being soaked with mask liquid. When the mask bag needs to be used, the barrier piece is removed from the mask bag, so that the mask liquid cavity and the mask cloth cavity are communicated, and the mask liquid can enter the mask cloth cavity, thereby facilitating the use of the mask bag.

[0007] A piston type barrier piece according to claim 1, comprising a barrier body, the barrier body is provided with a communication channel, the barrier body is slidably connected with a piston barrier rod for controlling the on-off of the communication channel, the barrier body is provided with a sliding channel for slidably cooperating with the piston barrier rod, the sliding channel is communicated with the communication channel, and the barrier body is connected with a detachable fixing plate for limiting the sliding of the piston barrier rod.

[0008] By adopting the technical scheme, when the mask bag is not used, the fixed plate limits the movement of the piston blocking rod, one end of the piston blocking rod is located at the connection between the communication channel and the sliding channel, thereby blocking the connection channel, so that the mask liquid in the mask liquid cavity cannot enter the mask cloth cavity, thereby preventing the mask liquid in the mask bag from mixing with the mask cloth. When the mask bag needs to be used, the fixed plate is removed from the piston blocking rod, the piston blocking rod can move along the depth direction of the sliding channel, the sliding cooperation between the piston blocking rod and the sliding channel plays a guiding and limiting role on the sliding of the piston blocking rod, thereby improving the stability of the sliding of the piston blocking rod, facilitating the piston blocking rod to move away from the connection between the communication channel and the sliding channel. At this time, the communication channel is in communication with the mask cloth cavity and the mask liquid cavity, the mask liquid enters the mask cavity through the communication channel, realizes the mixing of the mask liquid and the mask cloth, and is convenient to use. When there is a residual amount of mask liquid, the piston blocking rod can be moved to the original position, and the piston blocking rod blocks the mask liquid cavity and the mask cloth cavity again, thereby saving the residual amount of mask liquid and reducing the breeding of bacteria. Next time, the piston blocking rod is moved again.

[0009] Optionally, the piston blocking rod is connected with a moving block, the blocking body is provided with a moving cavity for clamping and sliding of the moving block, the moving block is connected with a guide block, the blocking body is provided with a guide groove for sliding cooperation with the guide block, and the guide groove and the sliding channel are in communication with the moving cavity.

[0010] By adopting the technical scheme, when the moving block is moved, the guide block slides along the guide groove, and the sliding cooperation between the guide block and the guide groove plays a guiding and limiting role on the sliding of the moving block, thereby improving the stability of the sliding of the moving block. The moving block limits the rotation of the piston blocking rod during movement, thereby improving the stability of the sliding of the piston blocking rod, facilitating the moving block to move out of the moving cavity, i.e. the piston blocking rod moves away from the connection between the communication channel and the sliding channel, and improving the efficiency of moving the piston blocking rod.

[0011] Optionally, the communication channel includes an inlet channel, an outlet channel and a connection channel, the sliding channel, the inlet channel and the outlet channel are in communication with the connection channel, one end of the piston blocking rod can extend into the connection channel, the inlet channel is located between the sliding channel and the connection channel, and the connection channel is located between the inlet channel and the outlet channel.

[0012] By adopting the technical scheme, when the mask bag is used, the one end of the piston blocking rod away from the moving block is moved to the connection position of the moving cavity and the sliding channel, at this time, the inlet channel is located between the piston blocking rods of the outlet channel. The mask liquid in the inlet channel, the outlet channel and the mask liquid cavity enters the connection channel through the inlet channel, so that the mask liquid entering the moving cavity through the sliding channel is prevented, and the waste of the mask liquid is avoided. The piston blocking rod is moved towards the outlet channel, the piston blocking rod is in movable abutment with the inner wall of the connection channel, so as to facilitate the mask liquid attached to the inner wall of the connection channel and the mask liquid in the connection channel to flow towards the outlet channel, the mask liquid enters the mask cloth cavity through the outlet channel, the mask liquid remaining in the connection channel is reduced, and the use amount of the mask liquid is improved.

[0013] Optionally, the blocking body is provided with a clearance slot, the clearance slot is in communication with the connection channel, the connection channel is located between the clearance slot and the sliding channel, and one end of the piston blocking rod can extend into the clearance slot.

[0014] By adopting the technical scheme, when the mask bag is not used, the piston blocking rod sequentially passes through the moving channel and the connection channel, and one end of the piston blocking rod is located in the clearance slot. The piston blocking rod blocks the opening of the inlet channel and the opening of the outlet channel at the same time, even if the mask liquid enters the connection channel through the inlet channel, the piston blocking rod blocks the opening of the outlet channel, so that the mask liquid in the connection channel is prevented from entering the mask cloth cavity through the outlet channel, a double-blocking effect is achieved, and the sealing effect is improved. When the piston blocking rod located at the connection position of the moving cavity and the sliding channel is moved towards the clearance slot, the outer surface of the piston blocking rod can be in movable abutment with the inner circumferential wall of the connection channel, the piston blocking rod drives the mask liquid in the connection channel to move towards the clearance slot, so that the mask liquid enters the outlet channel, the mask liquid entering the moving cavity through the sliding channel is prevented, and the waste of the mask liquid is avoided.

[0015] Optionally, the piston blocking rod is sleeved with an elastic gasket for abutting against the inner wall of the connection channel.

[0016] By adopting the above technical scheme, the elastic gasket provides a sealing effect, is used for filling the gap between the inner wall of the connecting channel and the piston blocking rod, the outer surface of the elastic gasket is attached to the inner wall of the connecting channel, the elastic gasket is tensioned to the inner wall of the connecting channel, and the stability of the piston blocking rod is improved. Even if the mask liquid enters the connecting channel through the inlet channel, the mask liquid cannot pass through the elastic gasket to enter the outlet channel, and the effect of three barriers is achieved, and the sealing effect is improved. When the piston blocking rod located at the connecting position of the moving cavity and the sliding channel is slid towards the direction close to the accommodation slot, the elastic gasket is in movable abutment with the inner wall of the connecting channel, so that the scraping effect of the elastic gasket on the inner wall of the connecting channel is improved, the mask is reduced to adhere to the inner wall of the connecting channel, and the use amount of the mask liquid is improved.

[0017] Optionally, the moving block is fixedly connected with a limiting block, and the blocking body is provided with a limiting sliding channel for sliding cooperation with the limiting block, and the limiting sliding channel is communicated with the moving cavity.

[0018] By adopting the above technical scheme, when the moving block is moved, the limiting block slides along the limiting sliding channel, and the sliding cooperation of the limiting block and the limiting sliding channel plays a guiding and limiting effect on the sliding of the moving block, so that the stability of the sliding of the moving block is improved, and the limiting block is away from the inner wall of the side of the piston blocking rod and the limiting sliding channel is away from the inner wall of the side of the piston blocking rod. When the limiting block abuts against one side of the inner wall of the limiting sliding channel, at this time, the piston blocking rod is separated from the connecting channel and located in the sliding channel, the movement of the moving block is prevented from being excessive, the piston blocking rod is prevented from being separated from the sliding channel, the mask liquid is prevented from entering the moving cavity through the sliding channel, and the waste of the mask liquid is avoided.

[0019] Optionally, the limiting block comprises a first connecting block obliquely connected to the moving block and a second connecting block obliquely connected to the first connecting block, and the second connecting block is provided with an inclined surface for abutting against the inner wall of the limiting sliding channel.

[0020] By adopting the technical scheme, when the moving block needs to be moved, one end of the finger abuts against the lower side of the second connecting block, and force is applied in a direction away from the sliding channel, the contact area between the finger and the second connecting block is increased, the friction between the finger and the second connecting block can be improved, the stability is improved, and the movement of the moving block is facilitated. The larger contact area can help to disperse the pressure between the finger and the second connecting block, and reduce the concentrated force on a specific point. The larger contact area can provide more control points, so that the finger is more likely to maintain an accurate posture and movement trajectory when operating the second connecting block. When the limiting block abuts against the inner wall of one side of the limiting sliding channel, the inclined surface is attached to the inner wall of one side of the limiting sliding channel, thereby increasing the contact area between the second connecting block and the inner wall of the limiting groove sliding channel, reducing the pressure of the second connecting block on the inner wall of the limiting groove sliding channel, and reducing the damage of the second connecting block and the blocking body due to abutment. If the second connecting block or the blocking body is worn out, the second connecting block moves excessively, and the piston blocking rod is separated from the sliding channel, the mask liquid enters the moving cavity through the sliding channel, and the mask liquid is wasted.

[0021] Optionally, the moving block is provided with a let-out hole.

[0022] By adopting the technical scheme, after the fixed plate is removed, the finger is inserted into the let-out hole, the let-out hole provides space for the insertion of the finger, the inner wall of the let-out hole is pressed in a direction away from the piston blocking rod, the contact area between the finger and the moving block is increased, and the piston blocking rod is moved. The let-out hole reduces the weight of the moving block and improves the effect of moving the moving block. The let-out hole reduces the use of moving block materials and reduces manufacturing costs.

[0023] Optionally, the blocking body is provided with an arc-shaped groove, the moving cavity and the sliding channel are in communication with the arc-shaped groove, and an end of the piston blocking rod away from the moving block is arc-shaped.

[0024] By adopting the technical scheme, when the piston blocking rod is installed, the piston blocking rod is aligned with the moving channel, and the piston blocking rod is moved in a direction close to the moving channel. Even if the piston blocking rod is misaligned with the moving channel, the end of the piston blocking rod with the arc surface is in active abutment with the arc-shaped groove, the arc-shaped groove plays a guiding and limiting role in the movement of the piston blocking rod, thereby guiding the piston blocking rod to be clamped into the connecting channel, and improving the installation efficiency of the piston blocking rod. The end of the piston blocking rod is arc-shaped, the contact area between the piston blocking rod and the arc-shaped groove is increased, and the damage of the piston blocking rod due to abutment is reduced.

[0025] In summary, the present application has at least one of the following beneficial technical effects:

[0026] 1. When the mask bag is not used, the piston blocking rod passes through the moving channel and the connecting channel in turn, and one end of the piston blocking rod is located in the accommodation slot. The piston blocking rod blocks the opening of the inlet channel and the opening of the outlet channel at the same time. Even if the mask liquid enters the connecting channel through the inlet channel, the piston blocking rod blocks the opening of the outlet channel, so as to prevent the mask liquid in the connecting channel from entering the outlet channel into the mask cloth cavity, thereby achieving the effect of double blocking and improving the sealing effect.

[0027] 2. When the piston blocking rod located at the connection between the moving cavity and the sliding channel slides towards the accommodation slot, the outer surface of the piston blocking rod can abut against the inner wall of the connecting channel, and the piston blocking rod drives the mask liquid in the connecting channel to move towards the accommodation slot, so that the mask liquid enters the outlet channel, and the situation that the mask liquid enters the moving cavity through the sliding channel is prevented, thereby avoiding the waste of the mask liquid.

[0028] 3. The elastic gasket provides a sealing effect and is used to fill the gap between the inner wall of the connecting channel and the piston blocking rod. The outer surface of the elastic gasket is attached to the inner wall of the connecting channel, and the elastic gasket is tensioned against the inner wall of the connecting channel, thereby improving the stability of the piston blocking rod. Even if the mask liquid enters the connecting channel through the inlet channel, the mask liquid cannot enter the outlet channel through the elastic gasket, thereby achieving the effect of triple blocking and improving the sealing effect.
