Description

Technical Field

[0001] The utility model relates to the technical field of exhibit cleaning tools, in particular to a sculpture cleaning device. Background Art

[0002] Sculpture, as a plastic art, is a visual art object made of material and means into a three-dimensional image. It has high appreciation value or collection value and is a common work of art in people's lives. Some small-scale figure sculptures are usually placed in exhibition halls for people to appreciate, and at the same time play a role in promotion and display. However, during the long-term display process, sculptures are inevitably contaminated by dust and need to be cleaned regularly.

[0003] At present, most of the cleaning of sculptures is done by staff using brushes, which may cause secondary adhesion of dust. In addition, due to the large number of details and textures on the figure sculptures themselves, it is often difficult to achieve effective cleaning by relying solely on brushes, resulting in a decline in cleaning quality, which is not conducive to actual work. Utility Model Content

[0004] The technical problem to be solved by the present invention is to address the above-mentioned technical deficiencies and provide a sculpture cleaning device. During the sculpture cleaning process, the suction holes are used to absorb negative pressure on the surrounding area, which can take away the floating dust, thereby avoiding the secondary fall of dust. At the same time, the fine lines and gaps can be flushed through the nozzle to remove the dirt adhering to the inside, effectively improving the overall cleaning quality.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention includes:

[0006] An outer shell is provided with a plurality of air suction holes at the bottom end of the outer shell, a transmission shaft is provided inside the outer shell, and the transmission shaft is respectively processed with an internal thread and an external thread with opposite rotation directions, and a first brush body and a nozzle are respectively provided under the outer shell, the first brush body is connected to the external thread, and the nozzle is connected to the internal thread.

[0007] Preferably, a support plate is provided above the outer shell; positioning posts symmetrically provided on the first brush body are slidably connected to the support plate, and the top ends of the positioning posts are threadedly connected to the transmission shaft.

[0008] Preferably, support columns are symmetrically provided above the support plate, and a motor connected to a transmission shaft is installed on the top of the support column.

[0009] Preferably, a guide groove is provided on the inner wall of the first brush body, and a guide strip cooperating with the guide groove is provided on the outer wall of the nozzle.

[0010] Preferably, an extension sleeve is provided above the first brush body.

[0011] Preferably, bristles are evenly arranged in the area around the nozzle.

[0012] Preferably, a cavity communicating with the air suction hole is provided on the top of the outer shell, and an air supply hole is provided on the cavity.

[0013] Preferably, a fixing ring is provided in the middle of the outer shell, and at least one exhaust pipe is provided on the fixing ring; and an adjusting chamber is provided at the top of the outer shell.

[0014] Preferably, a communicating hole cooperating with the air supply hole is provided on the outer wall of the regulating cavity, and a short sleeve connected with the exhaust pipe is provided on the bottom surface of the regulating cavity.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] 1. For cleaning the dust on the sculpture surface, the first brush body is used to sweep and remove it. For the more stubborn dirt in the lines and gaps, the transmission shaft is used to control the first brush body to retract and the nozzle to extend, and the cleaning agent is used to flush the area, greatly improving the cleaning quality.

[0017] 2. The first brush body and the nozzle are switched by controlling the transmission shaft, which can avoid interference during use. When the nozzle is spraying and flushing, it can also avoid wetting the first brush body and affecting subsequent cleaning. The overall structural design is reasonable.

[0018] 3. By adding an adjustment cavity, the connection between the cavity and the fixed ring can be switched, thereby meeting the demand for drying the inside of the outer shell and improving the stability of the internal structure operation;

[0019] 4. By adding an extension sleeve to the first brush body, the contact channel with the nozzle can be extended, thereby improving the stability of the nozzle, while reducing the length of the nozzle itself and facilitating processing and manufacturing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0030] Specific implementation method 1: Combination Figure 1-7 As shown, a sculpture cleaning device comprises: an outer shell 1, a plurality of air suction holes 101 are provided at the bottom end of the outer shell 1, a transmission shaft 2 is provided inside the outer shell 1, and the transmission shaft 2 is processed with an internal thread and an external thread with opposite rotation directions, a first brush body 3 and a nozzle 4 are provided below the outer shell 1, the first brush body 3 is connected to the external thread, and the nozzle 4 is connected to the internal thread;

[0031] When the sculpture needs to be cleaned, the dust on the surface is removed by opening the negative pressure device, which is connected to the suction hole 101, and performing negative pressure adsorption on the bottom area of the outer shell 1. Then the staff holds the outer shell 1 and uses the first brush body 3 to sweep and remove the dust on the surface of the sculpture. The dust floating up under the sweeping action is adsorbed by the negative pressure, which can effectively keep the surrounding environment clean and avoid secondary falling. However, for the lines or gaps, it is impossible to effectively clean them by relying solely on the first brush body 3. At this time, the first brush body 3 is driven to retract into the inner part of the outer shell 1 through the transmission shaft 2, and the nozzle 4 is extended out of the outer shell 1 in the opposite direction. The nozzle 4 is connected to the liquid supply device through a pipeline to generate detergent for flushing. After a period of rest, it is cleaned with a rag to effectively improve the cleaning quality.

[0032] The preferred embodiment, combined with Figure 3 and Figure 4As shown, a support plate 102 is provided above the outer shell 1; two threaded positioning columns 301 are provided on the first brush body 3, and the positioning columns 301 pass through the support plate 102 to form a sliding connection. At the same time, a contact plate connected to the outer wall of the transmission shaft 2 is fixed at the end by a nut, and the middle part of the contact plate is threadedly connected to the transmission shaft 2; the positioning columns 301 are slidably connected to the support plate 102, thereby realizing the guiding and positioning function during the displacement of the first brush body 3.

[0033] The preferred embodiment, combined with Figure 3-4 As shown, two support columns 103 are symmetrically fixed above the support plate 102, and an intermediate shell is fixed to the top of the support column 103 through a nut, and an electric motor is installed on the intermediate shell. The motor is connected to the transmission shaft 2 to realize drive control of the transmission shaft 2.

[0034] The preferred embodiment, combined with Figure 5 As shown, the inner wall of the first brush body 3 is processed with at least one guide groove 302, preferably two, and symmetrically arranged, which can improve the stability during displacement. The outer wall of the nozzle 4 is processed with a guide bar 401, and the guide bar 401 is slidably connected to the guide groove 302. The cross-sectional shape of the guide groove 302 is similar to a rectangle, and can also be a semicircular structure, etc., to achieve positioning of the nozzle 4 in the circumferential direction, thereby achieving displacement under the drive of the transmission shaft 2.

[0035] The preferred embodiment, combined with Figure 5 As shown, an extension sleeve 303 is provided above the first brush body 3, which increases the contact channel with the nozzle 4, so that the length size can be processed smaller and more reasonably during the processing of the nozzle 4, which is convenient for manufacturing and improves the stability of the support.

[0036] The preferred embodiment, combined with Figure 5 and Figure 8 As shown, bristles 402 are evenly arranged in the area around the nozzle 4. After flushing, the bristles 402 can be used to brush the gaps to facilitate the contact between the detergent and the dirt. At the same time, the bristles 402 also limit the wide spread of the spray.

[0037] The preferred embodiment, combined with Figure 3-4 As shown, a cavity 104 connected to the air intake hole 101 is provided on the top of the outer shell 1, and an air supply hole 105 is provided on the cavity 104. The air supply hole 105 is connected to the negative pressure device through a pipeline, and the arrangement of the cavity 104 facilitates the simultaneous connection of each air intake hole 101 with the negative pressure device.

[0038] The preferred embodiment, combined with Figure 3 、 Figure 6 、 Figure 7 and Figure 8As shown, a fixing ring 5 is provided in the middle of the outer shell 1, and at least one exhaust pipe 501 is provided on the fixing ring 5, and the lower part of the exhaust pipe 501 is connected with the internal space of the outer shell 1; at the same time, a slidable adjustment chamber 6 is provided on the top of the outer shell 1. By changing the position of the adjustment chamber 6, the connection with the air supply hole 105 or the exhaust pipe 501 is achieved, and the suction switching is realized. When moisture appears inside the outer shell 1, it can be adsorbed through the exhaust pipe 501 to accelerate the air flow and achieve internal drying.

[0039] The preferred embodiment, combined with Figure 6 and Figure 7 As shown, a connecting hole 601 cooperating with the air supply hole 105 is provided on the outer wall of the regulating chamber 6, and a short sleeve 602 connected with the exhaust pipe 501 is provided on the bottom surface of the regulating chamber 6. Under normal circumstances, the connecting hole 601 and the air supply hole 105 are in a connecting state. When it is necessary to adsorb the inside of the outer shell 1, the regulating chamber 6 is pushed downward so that the air supply hole 105 and the connecting hole 601 are in a dislocated state, and the top end of the exhaust pipe 501 enters the interior of the regulating chamber 6 to achieve connection, thereby achieving the switching effect. Specific implementation method 2

[0041] Combine Figure 4 and Figure 7 As shown, the positioning sliding hole 603 is slidably connected to the support column 103 to achieve positioning and guiding of the adjustment cavity 6, ensuring that the displacement of the adjustment cavity 6 is stable and reliable. Specific implementation method three

[0043] Combine Figure 4 As shown, a liquid supply pipe connected to the interior is processed above the nozzle 4 and is connected to the pipeline on the intermediate shell through a hose. When the connection is maintained, the displacement adjustment of the nozzle 4 will not be affected.

[0044] Combine Figure 6 As shown, the regulating chamber 6 also has two suction pipes communicating with the interior, and the suction pipes are connected to the external negative pressure device through rubber hoses. When kept connected, it is convenient for the staff to operate.

[0045] The cleaning agent used for sculptures is a mixture of weakly acidic fragrance-free soap and water. After rinsing, let it stand for 7-15 minutes to allow the solvent to fully react with the dirt and improve the cleaning effect.

[0046] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
