In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example one

The embodiment of the present invention provides a brushing device, which is used for brushing a surface 800 to be brushed (see fig. 8, 9, 16, and 17), wherein the coating 700 may be paint or latex, and the surface 800 to be brushed may be a plane or a curved surface.

As shown in fig. 1 to 4, in this embodiment, the painting device includes a connecting base 100, a handle 200 connected to the connecting base 100, two parallel and spaced rolling brush cylinders 300 rollably connected to the connecting base 100, and a supply assembly 400 for supplying paint 700, wherein the supply assembly 400 has a discharge port 401 for the paint 700 to overflow, and the discharge port 401 is located between the two rolling brush cylinders 300 and faces a surface to be painted 800.

Based on the above structure, in the using process, firstly, the user grasps the handle 200 and makes the two rolling brush cylinders 300 abut against the surface 800 to be brushed, secondly, the coating 700 is discharged from the discharge port 401 and coated on the surface 800 to be brushed, and then, the two rolling brush cylinders 300 roll, thereby uniformly coating the coating 700 on the surface 800 to be brushed. Through the arrangement of the feeding assembly 400, when the painting device needs the paint 700, the paint is supplied by the feeding assembly 400 and is directly supplied to the surface 800 to be painted, so that the rolling brush drum 300 does not need to move back and forth between the surface 800 to be painted and the paint bucket, the operation difficulty is reduced, the time of moving back and forth between the surface 800 to be painted and the paint bucket is reduced, and the painting efficiency is improved. In addition, since the outlet 401 of the supply assembly 400 is located between the two rolling brush drums 300, the rolling brush drum 300 located at the rear side can apply the coating material 700 discharged from the outlet 401 to the surface 800 to be brushed in time during the rolling of the two rolling brush drums 300.

As shown in fig. 1 to 4, the feeding assembly 400 includes a discharging brush head 410, a storage container 420 for storing the paint 700, and a feeding mechanism 430 for extruding the paint 700 from the storage container 420 to the discharging brush head 410, the discharging brush head 410 is disposed between the two rolling brush cylinders 300 and fixed to the connection seat 100, and the discharging outlet 401 is disposed on the discharging brush head 410 and communicated with the storage container 420. Based on this, during painting, through the arrangement of the feeding mechanism 430, the paint 700 can be extruded from the storage container 420 to the discharge port 401, so that during the process of coating the paint 700, the paint can be continuously extruded from the storage container 420 to the discharge brush head 410 and then discharged from the discharge port 401 of the discharge brush head 410, and therefore, the rolling brush barrel 300 does not need to move back and forth between the surface 800 to be painted and the paint barrel.

As shown in fig. 1 to 4, as shown in fig. 2, the supply assembly 400 includes a weight member 440, and a first connection hose 450 disposed in the magazine 420, the first connection hose 450 having a fixed end fixedly connected to the magazine 420 and abutting against an outlet of the magazine 420, and a free end capable of abutting against any position in the magazine 420, the weight member 440 being connected to the free end of the first connection hose 450. Based on this, through the arrangement of the weight member 440, the acting force of the feeding pipe orifice of the first connecting hose 450 on the weight member 440 can be always at the low point position in the storage container 420, and in the working process, the storage container 420 may change different spatial positions, which is beneficial to ensuring that the feeding pipe orifice of the first connecting hose 450 is always below the liquid level of the coating 700, and when the pneumatic pump inflates the storage container 420, the coating 700 can enter the discharging brush head 410 through the first connecting hose 450.

And the feeding mechanism 430 includes a pneumatic pump for inflating the magazine 420 to squeeze the coating material 700 from the magazine 420 to the first connection hose 450, and a first check valve 460 provided between the pneumatic pump and the magazine 420 and allowing gas to enter the magazine 420 from the pneumatic pump, the first connection hose 450 extending into the magazine 420. Based on the structure, the adoption of the pneumatic pump is beneficial to simplifying the structure, and in other embodiments, structures such as an oil pump and the like can be adopted; in this embodiment, the pneumatic pump may be specifically an electric pneumatic pump or a manual pneumatic pump, wherein the use of the electric pneumatic pump is beneficial to reduce the labor intensity of the user, and the use of the manual pneumatic pump is beneficial to reduce the cost. Wherein, a first one-way valve 460 which only supplies gas from the pneumatic pump to the storage container 420 is arranged between the pneumatic pump and the storage container 420, and the backflow to the pneumatic pump can be prevented through the arrangement of the first one-way valve 460. In an implementation, the air inlet for the air output by the air pressure pump to enter the magazine 420 may be directly provided at any position of the magazine 420, such as at the connection between the magazine 420 and the handle 200, or may be provided on a cover structure for covering the material inlet of the magazine 420, wherein the first check valve 460 may be disposed at the air inlet.

Further, as shown in fig. 1 to 4, the feeding mechanism 430 and the magazine 420 are respectively connected to two ends of the handle 200, and the handle 200 is provided with an air guide channel 201 for communicating the magazine 420 and the air pressure pump. The pneumatic pump is arranged at one end, far away from the material storage container 420, of the handle 200, so that the weight of the two ends of the handle 200 can be balanced, the air guide channel 201 is arranged in the handle 200, the situation that a pipeline is arranged outside the handle 200 is avoided, parts are reduced, and maintenance is facilitated.

In addition, in this embodiment, if the air guide channel 201 of the handle 200 is not directly connected to the magazine 420, the handle 200 and the magazine 420 are connected by a third connecting hose 480 as shown in fig. 2.

Further, as shown in fig. 2, a feeding port (not labeled) is opened on the storing container 420, and the discharging brush head 410 is covered on the feeding port. Based on the structure, firstly, the discharging brush head 410 is taken away from the feeding port, namely the feeding port is opened, and the coating 700 can be added into the storage container 420, so that the coating 700 in the storage container 420 can be supplemented in time after being used up, secondly, the storage container 420 is close to the discharging brush head 410, the distance between the storage container 420 and the discharging port 401 can be shortened, and the coating 700 can be extruded from the storage container 420 to the discharging port 401 by the air pressure pump only with small air pressure. Specifically, in this embodiment, as shown in fig. 2, the discharging brush head 410 includes a plug-in pipe detachably plugged in the material inlet, and an outer pipe wall of the plug-in pipe abuts against an inner side wall of the material inlet.

In this embodiment, the handle 200 is rotatably coupled to the magazine 420 such that the angular relationship between the handle 200 and the work surface can be adaptively adjusted during translation of the work surface formed between the two roller brush cartridges 300, and the user can move the handle 200 along its length without shifting its position. Of course, in other embodiments, the handle 200 may be directly rotatably connected to the connection holder 100.

Example two

The difference between the present embodiment and the first embodiment is that, as shown in fig. 5 to 9, the discharging brush head 410 includes a brush head seat 411, a brush head sleeve 412 and a valve 413. The brush head seat 411 is provided with a brush seat inlet 411a matched with the feeding assembly 400 and a brush seat outlet 411b communicated with the brush seat inlet 411a, so that when the feeding assembly 400 feeds the discharging brush head 410, the coating 700 enters from the brush seat inlet 411a, wherein the coating 700 can be paint or latex. The brush head holder 412 is fixed to the brush head holder 411, and includes a discharge head 4121 and a connection pipe 4122 connecting the brush head holder 411 and the discharge head 4121. The discharge head 4121 is provided with a discharge port 401 communicated with the connecting pipe 4122, and the discharge port 401 is provided at an end of the discharge head 4121 far away from the brush head seat 411. The connection tube 4122 includes an extension portion 4122a connected to the brush holder 411 and extending along the opening direction of the brush holder outlet 411b and having elastic recovery, and a pressing portion 4122b connected to the end of the extension portion 4122a away from the connection seat 100 and extending inward, the pressing portion 4122b has a movement tendency toward the valve 413 under the elastic recovery force of the extension portion 4122a, the valve 413 is disposed between the pressing portion 4122b and the brush holder 411, the pressing portion 4122b is in sealing contact with the valve 413 when the valve 413 is subjected to an external force in the opening direction of the brush holder outlet 411b, and is released from sealing contact with the valve 413 when the discharge head 4121 is subjected to an external force perpendicular to the opening direction of the brush holder outlet 411 b. In this embodiment, the discharging head 4121 is connected to the inner edge of the pressing portion 4122b and extends in a direction away from the brush head seat 411.

Based on the above structure, since the extension 4122a has elastic recovery, the discharging brush head 410 can have three states according to the stress condition of the extension 4122a, specifically as follows:

as shown in fig. 6, the discharging brush head 410 is in a free state, that is, the feeding assembly 400 does not yet feed the paint 700 to the discharging brush head 410, the pressing part 4122b has a moving tendency toward the valve 413 under the elastic restoring force of the extending part 4122a, the pressing part 4122b presses the valve 413 against the brush head seat 411 and blocks the brush seat outlet 411b, so as to prevent the paint 700 from flowing out of the brush seat outlet 411 b;

as shown in fig. 8, the discharging brush head 410 is in a static pressurized state, that is, the feeding assembly 400 feeds the paint 700 to the discharging brush head 410, wherein in order to feed the paint 700 to the discharging brush head 410, a certain pressure needs to be applied to the paint 700 by the feeding assembly 400 to feed the paint 700 to the discharging brush head 410, and the pressure applied to the paint 700 by the feeding assembly 400 is transmitted to the valve 413, so that the valve 413 receives an external force in the opening direction of the brush holder outlet 411b to counteract the elastic restoring force of a part of the extending portion 4122a, so that the valve is separated from the brush holder 411, and at this time, the paint 700 still cannot smoothly overflow to the discharging brush head 4121 because the bonding between the pressing portion 4122b and the valve 413 is still tight;

as shown in fig. 9, the discharging brush head 410 is in a working state, that is, on the basis that the discharging brush head 410 is in a static pressurized state, the discharging head 4121 is pressed against the working surface and drags the discharging brush head 410, at this time, the discharging head 4121 will generate friction with the working surface, the working surface will generate lateral acting force on the discharging head 4121, and since the extending portion 4122a has elastic recovery, the lateral acting force will make the extending portion 4122a generate oblique deformation, and in the process of generating deformation of the extending portion 4122a, a gap will be generated between the pressing portion 4122b and the valve 413, the paint 700 can overflow to the discharging head 4121 from the gap, and the discharging brush head 410 is dragged back and forth on the working surface constantly, and the paint 700 can overflow to the discharging head 4121 continuously, thereby realizing continuous feeding.

Based on the above, through brush head seat 411, brush head cover 412 and valve 413 setting, ejection of compact brush head 410 can receive the exogenic action of perpendicular to brush holder export 101b opening direction when ejection of compact head 210 is ejection of compact, just the ejection of compact is just ejection of compact when ejection of compact brush head 410 carries out the coating operation, the ejection of compact time of ejection of compact brush head 410 can adapt to the activity duration of ejection of compact brush head 410, and can not be in the ejection of compact of non-coating time, and for prior art, this ejection of compact brush head 410 has simple structure, and the manufacturing of being convenient for, and the maintenance is convenient for. Moreover, because the pressing part 4122b releases the sealing fit with the valve 413 when the discharging head 4121 receives an external force perpendicular to the opening direction of the brush holder outlet 411b, the acting force applied to the coating 700 only needs to be slightly larger than the force for making the coating 700 reach the brush holder outlet 411b, the required extrusion force is small, and thus, the feeding assembly only needs to adopt small power to convey the coating 500.

In addition, in the process of feeding the discharging brush head 410 by the feeding mechanism 430, the discharging head 4121 moves towards the surface 800 to be brushed under the pressure of the paint 700 until the discharging head 4121 collides with the surface 800 to be brushed, at this time, the discharging brush head 410 reaches a static pressurized state, the discharging head 4121 of the discharging brush head 410 can adapt to the surface 800 to be brushed in a self-adaptive manner, the discharging head 4121 does not need to collide with the surface 800 to be brushed before operation, and the rolling brush barrel 300 is more uniform when the paint 700 is rolled and brushed; when the feeding mechanism 430 releases the feeding to the discharging brush head 410, the coating material 700 releases the pressure on the coating material head 4121, and at this time, the coating material head 4121 is separated from the surface to be brushed 700.

As shown in fig. 6 to 9, the brush holder inlet 411a and the brush holder outlet 411b are communicated through a linear channel 411c, and on this basis, the discharging brush head 410 comprises a guide rod 414, the guide rod 414 is connected to the side of the valve 413 facing the brush holder seat 411 and is arranged in the linear channel 411c, wherein the cross section of the guide rod 414 is smaller than that of the linear channel 411c, so as to avoid the guide rod 414 from blocking the coating 700 in the linear channel 411 c. With this structure, the movement direction of the valve 413 is limited by the guide rod 414, and the valve 413 can only move along the extension direction of the linear passage 411c, so that the valve 413 can be reset to the initial position by the extension 4122a when the supply assembly 400 stops supplying.

In this embodiment, the cross-sectional shape of the guide rod 414 matches the cross-sectional shape of the linear channel 411c, and the cross-sectional shape of the guide rod 414 is slightly smaller than the cross-sectional shape of the linear channel 411c, ensuring that the valve 413 can move in a predetermined direction.

In other embodiments, the cross-section of the guiding rod 414 may be circular, so that when the valve 413 is in the process of moving, for example, when encountering a foreign object, the discharging head 4121 is subjected to an external force increasing in a direction perpendicular to the opening direction of the brush holder outlet 411b, and the valve 413 may rotate to a certain extent, which is beneficial to avoiding the foreign object.

Further, the valve 413 and the guide rod 414 are integrally arranged, so that the valve 413 and the guide rod 414 are formed in one step in the production process, and are not required to be assembled after being formed respectively, and the production efficiency is improved.

As shown in fig. 6, 8 and 9, the connection tube 412 includes a fixing portion 4122c connected to a tube end of the extension portion 4122a facing away from the pressing portion 4122b and extending outward and fixedly connected to the brush head holder 411. Based on the structure, the fixing portion 4122c needs to be in fixed sealing contact with the brush head seat 411, the fixing portion 4122c is in surface contact with the brush head seat 411, the fixing portion 4122c can be in fixed sealing contact with the brush head seat 411 only by applying a proper fastening force to the fixing portion 4122c towards the brush head seat 411, and the structure is simple and convenient to implement.
