Description

Technical Field

[0001] This utility model relates to the field of furniture waxing technology, and in particular to a wooden furniture waxing device. Background Technology

[0002] Waxing the surface of wooden furniture is an important process in both traditional and modern furniture manufacturing and maintenance. It aims to enhance the furniture's appearance, giving it a warm luster and delicate feel, and effectively protecting the wood from cracking, moisture, staining, and wear. Currently, there are various methods for waxing wooden furniture, ranging from traditional hand rubbing and brushing to using auxiliary spraying or rolling tools.

[0003] However, in practical applications, existing wood furniture spraying or waxing devices are prone to uneven wax distribution when using traditional manual application methods, resulting in noticeable wax marks, patches, or localized accumulations, which affects the overall visual effect of the furniture. Some simple spraying devices have poor atomization effects, easily producing large droplets or "sags," making it difficult to form a uniform and delicate wax film.

[0004] Furniture waxes (especially natural waxes, beeswax, carnauba wax, or some mixed hard waxes) are fluid at certain temperatures, but they tend to solidify or their viscosity increases sharply at room temperature or slightly lower temperatures. This makes it easy for the nozzles, valves, and wax delivery channels of the spraying device to become clogged. Cleaning and maintenance of existing devices often requires disassembling multiple parts, which is cumbersome and time-consuming, affecting work efficiency and the continuous availability of the equipment.

[0005] Different types of wood, finish requirements, or seasonal temperature changes may necessitate the use of waxes with different formulations and viscosities. Many existing wax spraying devices, especially purely mechanical ones, are often designed for waxes of specific viscosities. When the wax viscosity changes, their spraying effect is greatly reduced, or they may even fail to function properly. Therefore, there is an urgent need for a wax spraying device for wooden furniture. Utility Model Content

[0006] The purpose of this utility model is to address the deficiencies in the existing technology by proposing a wax spraying device for wooden furniture.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A wooden furniture waxing device, comprising:

[0009] The main shell has a wax storage chamber for storing wax and suitable for gravity-fed wax supply. A wax outlet structure is provided at the end of the wax storage chamber.

[0010] The auxiliary extrusion mechanism is used to extrude wax from the wax storage chamber.

[0011] The nozzle assembly is connected to the wax outlet structure and includes:

[0012] The system includes an air pressurization tube, a pneumatic turbine, a rotary atomizer, and a wax delivery path. The wax delivery path is used to deliver wax from the wax outlet structure to the rotary atomizer. The rotary atomizer is connected to the pneumatic turbine via a connecting rod.

[0013] Furthermore, a connecting sleeve is provided at the connection between the connecting rod and the rotary atomizer. The connecting sleeve has a conical structure and several striking protrusions are provided on the outer wall of the connecting sleeve.

[0014] Furthermore, the air pressurization tube is integrated into the air inlet of the main housing and drives the rotating atomizer through the flow of air.

[0015] Furthermore, the rotary atomizer has a conical structure with its opening extending in the direction of wax flow. The connecting sleeve is installed in the center of the rotary atomizer, and several jet holes are provided on the rotary atomizer.

[0016] Furthermore, the outer wall of the rotary atomizer is fitted with an auxiliary shield that matches it. The auxiliary shield has several shield holes, which are tapered holes that taper towards the axis of the rotary atomizer.

[0017] Furthermore, a guide arc plate is provided between the rotary atomizer and the wax storage chamber, and a spring scraper is provided on the inner wall of the guide arc plate. One end of the spring scraper and the guide arc plate are hinged together, and the spring scraper is stretched by the spring under normal conditions to form an angle with the guide arc plate.

[0018] Furthermore, the wax outlet structure includes a partition sleeve, inside which is provided an outflow sleeve. The outflow sleeve has a conical structure and gradually narrows towards the direction of wax outlet flow. A connecting groove is provided at the bottom of the outflow sleeve, and several auxiliary through holes are provided on the partition sleeve.

[0019] Furthermore, the auxiliary extrusion mechanism includes an extrusion baffle that cooperates with the partition sleeve. Several hollow liquid replenishment pipes are provided in the middle of the extrusion baffle. The hollow liquid replenishment pipes penetrate the main shell and extend to the outside of the main shell. A pressure plate is provided at the end of the hollow liquid replenishment pipe away from the extrusion baffle.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] Driven by airflow, the pneumatic turbine rotates at high speed via a connecting rod, which can more effectively disperse the wax liquid into uniform and fine droplets, resulting in a thinner and more uniform wax film. This significantly improves the finish and aesthetics of the waxed surface, while reducing wax waste. The layered sleeve and conical outflow sleeve can stabilize and guide the flow of the wax liquid, ensuring the stability of the wax spraying.

[0022] The spray holes on the conical structure of the rotary atomizer facilitate efficient atomization and uniform distribution of the wax liquid under centrifugal force, enhancing the controllability of wax output and adaptability to wax liquids of different viscosities. It also allows the operator to apply additional pressure manually or by adding a drive assembly to assist the wax flow when needed. This is particularly effective for handling wax liquids with slightly higher viscosity or those whose fluidity deteriorates at low temperatures. This broadens the device's applicability to different wax liquids, reduces manufacturing costs and failure rates, and improves the equipment's durability and applicability in various environments. It has significant practical value for improving the quality and efficiency of waxing wooden furniture. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0032] Reference Figure 1-5 A wooden furniture waxing device includes a main housing 100. Inside the main housing 100, a wax storage chamber 200 is provided. The wax storage chamber 200 is used to store liquid wax to be used. At the end of the wax storage chamber 200, a wax outlet structure 300 is connected and provided, through which the wax is discharged.

[0033] An auxiliary extrusion mechanism 400 is also provided, which can apply additional pressure to the wax in the wax storage chamber 200 to assist its outflow. The atomization function is achieved by a nozzle assembly 500, which is detachably connected to the wax outlet structure 300. The nozzle assembly 500 integrates: an air pressurization pipe 501 for introducing or generating pressurized air; a pneumatic turbine 506 as a power conversion element; a rotary atomizer 502 for dispersing liquid wax into fine droplets; and a wax delivery path consisting of relevant pipes or chambers, which is responsible for accurately delivering the wax flowing from the wax outlet structure 300 to the rotary atomizer. The atomizer 502 operates within a certain area. The rotary atomizer 502 and the pneumatic turbine 506 are mechanically connected by a connecting rod 601. During operation, under the action of gravity and / or the auxiliary extrusion mechanism 400, the wax liquid flows from the wax liquid storage chamber 200 through the wax liquid outlet structure 300 and the wax liquid delivery path to the rotary atomizer 502. At the same time, the air pressurization pipe 501 provides compressed air to drive the pneumatic turbine 506 to rotate at high speed. The pneumatic turbine 506 drives the rotary atomizer 502 to rotate at the same speed through the connecting rod 601. The wax liquid that reaches the surface of the rotary atomizer 502 is thrown out and atomized into a uniform wax mist under the action of centrifugal force generated by the high-speed rotation, and sprayed onto the surface of the wooden furniture.

[0034] A connecting sleeve 600 is specially provided at the connection between the connecting rod 601 and the rotary atomizer 502. The connecting sleeve 600 is preferably conical in shape, and several striking protrusions 602 are provided on the outer wall of the connecting sleeve 600. The rotary atomizer 502 is also conical in shape, and its opening gradually expands in the direction of wax flow, forming a shape similar to a trumpet. The connecting sleeve 600 is installed in the center of the rotary atomizer 502. Several jet holes 503 are opened on the conical wall of the rotary atomizer 502. The compressed air flow causes the pneumatic turbine 506 to rotate at high speed, and the connecting rod 601... 1. Power is transmitted to the connecting sleeve 600, which in turn drives the rotary atomizer 502 to rotate. The conical structure and the expanded opening of the rotary atomizer 502 allow the wax liquid to spread on its inner surface and accelerate under the action of centrifugal force. The wax liquid is finally ejected at high speed through the spray hole 503 and atomized. During the rotation, the striking protrusions 602 on the outer wall of the connecting sleeve 600 generate a small, high-frequency knocking or disturbance due to airflow disturbance, which prevents unnecessary adhesion or dripping of the wax liquid before it is sprayed out. At the same time, it pre-disperses the high-speed wax liquid for further dispersion and refinement of the wax mist, thereby improving the atomization quality.

[0035] The air pressurization pipe 501 serves as the power source for driving the pneumatic turbine 506 and thus rotating the rotary atomizer 502. The air pressurization pipe 501 is integrated at the air inlet of the main housing 100. The main housing 100 has a dedicated air inlet. The air pressurization pipe 501 is connected to this inlet via a tubular structure for guiding and accelerating airflow, and is connected to an external air source interface. The pressurized airflow introduced or generated through the air pressurization pipe 501 is guided and impacts the blades of the pneumatic turbine 506, causing the pneumatic turbine 506 to rotate at high speed. Since the pneumatic turbine 506 is connected to the rotary atomizer 502 through the connecting rod 601, the rotary atomizer 502 also rotates at high speed, thus achieving its atomization function. The air pressurization pipe 501 serves as the inlet and channel of the pneumatic system, guiding the airflow with a certain pressure to the pneumatic turbine 506. The energy of the airflow is converted into the mechanical rotational energy of the pneumatic turbine 506, and the rotational energy is then transmitted to the rotary atomizer 502 through the connecting rod 601 to achieve its high-speed rotation and centrifugal atomization of the wax liquid.

[0036] The outer wall of the rotary atomizer 502 is fitted with an auxiliary shield 700 that fits tightly therewith. The shape of the auxiliary shield 700 is adapted to the shape of the rotary atomizer 502 and forms a cylindrical shape with the rotary atomizer 502, constraining the wax spray channel. Several shield holes 701 are opened on the wall of the auxiliary shield 700. The shield holes 701 are tapered holes that taper towards the axis of the rotary atomizer 502, that is, the outer diameter of each shield hole 701 is larger than the inner diameter, forming a miniature nozzle effect. The initially atomized wax droplets sprayed from the spray hole 503 of the rotary atomizer 502 will pass through the shield holes 701 on the auxiliary shield 700. Since the shield holes 701 are tapered holes that taper towards the axis, they will further guide, constrain, and atomize or focus the wax mist that passes through, thereby making the final sprayed wax mist shape more regular and controllable, which helps to improve the spraying accuracy and reduce the scattering and waste of wax.

[0037] Between the rotary atomizer 502 and the wax storage chamber 200, a guide arc plate 504 is provided. The inner surface of the guide arc plate 504 is a smooth arc surface used to guide the flow of wax. A spring scraper 505 is also provided on the inner wall of the guide arc plate 504. The spring scraper 505 and one end of the guide arc plate 504 are connected by a hinge, such as a small pin, so that the spring scraper 505 can swing around the hinge point. A spring is provided on the back of the spring scraper 505 or in its connecting mechanism. The spring causes the spring scraper 505 to be stretched by the spring force under normal conditions, that is, when there is no strong flow of wax liquid or no external force, forming a specific preset angle with the inner wall of the guide arc plate 504. When the liquid wax flows through the guide arc plate 504, its arc-shaped inner wall helps to guide the flow smoothly. Due to its elastic installation and the angle formed with the inner wall of the guide arc plate, the spring scraper 505 can slightly scrape the inner wall of the guide arc plate when the wax liquid flows through, preventing the wax liquid, especially wax with slightly higher viscosity or wax that is easy to cool and solidify, from excessively accumulating or forming a solidified layer here, keeping the wax liquid channel unobstructed, and at the same time playing a certain role in pre-dispersing or guiding the flowing wax liquid, so that it enters the rotary atomizer 502 more evenly. When large wax blocks or impurities pass through, the spring scraper can elastically retract. In addition, when rotating at high speed, the centrifugal force overcomes the spring force, causing the spring scraper 505 and the guide arc plate 504 to overlap, acting as a baffle and creating a large gap, which allows the dispersed wax liquid at the connecting sleeve to flow out smoothly. At low speed, the spring rebounds and scrapes.

[0038] The wax outlet structure 300 includes an outer partition sleeve 301. Inside the partition sleeve 301, an outlet sleeve 302 is coaxially or eccentrically arranged. The outlet sleeve 302 itself has a conical structure, and its taper is designed to gradually shrink in the direction of wax outlet flow. At the bottom of the outlet sleeve 302, that is, the lowest point of its inner cavity or a specific position, at least one connecting groove 303 is provided. Meanwhile, several auxiliary through holes 304 are also provided on the wall of the outer partition sleeve 301. The wax liquid first enters the annular space between the partition sleeve 301 and the outflow sleeve 302 from the wax liquid storage chamber 200. Then, the wax liquid enters the inner cavity of the outflow sleeve 302 through the connecting groove 303 at the bottom of the outflow sleeve 302, and flows out rapidly along the tapered inner wall that gradually narrows towards the outlet. The tapered structure helps to stabilize the liquid flow and may prevent larger impurities from passing through to a certain extent. The auxiliary through holes 304 provided on the partition sleeve 301 are used to balance the internal and external pressures and allow some air bubbles to escape. At the same time, the auxiliary extrusion mechanism 400 can pressurize by manual or equipment drive, which can accelerate the liquid flow at this point and achieve fine adjustment, preliminary filtration or flow stabilization of the wax liquid flow.

[0039] The auxiliary extrusion mechanism 400 includes an extrusion baffle 401. The shape and installation position of the extrusion baffle 401 allow it to cooperate with the partition sleeve 301 in the wax outlet structure 300 to apply pressure to the wax inside. At the center of the extrusion baffle 401, several hollow replenishment pipes 402 are provided. One end of each hollow replenishment pipe 402 is connected to the wax-facing side of the extrusion baffle 401, and the other end passes through the wall of the main housing 100 and extends to the outside of the main housing 100. The ends of the hollow replenishment pipes 402 away from the extrusion baffle 401 are connected to or act on a pressure plate 403. When auxiliary extrusion of the wax is required, the operator can pressurize the main housing... Pressure is applied to the external pressure plate 403, either by hand or through an external drive component such as a telescopic motor. This pressure is transmitted to the extrusion baffle 401 via the hollow liquid replenishment pipe 402, causing the extrusion baffle 401 to move towards the wax liquid. This extrusion compresses the wax liquid in the wax liquid storage chamber 200 or the wax liquid to be discharged through the partition sleeve 301, causing it to flow more quickly to the nozzle assembly 500. In addition to transmitting pressure, the hollow liquid replenishment pipe 402 may also balance the air pressure inside the wax liquid storage chamber 200 during the extrusion process, allowing air to be discharged from the storage chamber during extrusion or replenishing air after the wax liquid is consumed, preventing the formation of negative pressure that affects the flow of wax liquid.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
