Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0041] like Figure 1 As shown, this exemplary embodiment provides a tongue brush, which includes:

[0042] Brush handle 200;

[0043] A brush head 100, the brush head 100 is connected to a brush handle 200;

[0044] A plurality of scrapers 300 are arranged at intervals along the length direction of the brush head 100, and each scraper 300 is disposed around the circumferential surface of the brush head 100; the plurality of scrapers 300 include at least one scraper group with gaps of varying widths.

[0045] The tongue brush in the embodiment of the present application can be used to clean tongue coating, milk stains, rice stains, etc. on the tongue, wherein the brush handle 200 is used for the user to hold, the brush head 100 is used to extend into the user's mouth, and the scraper 300 on the brush handle 200 is used to scrape the stains on the user's tongue off the tongue.

[0046] like Figure 1 As shown, Figure 1The up and down direction in the shown orientation is the length direction of the brush head 100. A plurality of scrapers 300 are arranged in the length direction of the brush head 100. Each scraper 300 surrounds the brush head 100 in the horizontal direction and is connected to the surface of the brush head 100. There is a gap between adjacent scrapers 300.

[0047] In the embodiment of the present application, along the circumferential direction of the brush head 100, the plurality of scrapers 300 include at least one group of scraper blades with gaps having varying widths.

[0048] For example, Figure 2 As shown, in the embodiment of the present application, the scraper blade group with gaps having varying widths includes: a bent scraper blade 310 in a bent shape in the circumferential direction of the brush head 100 , and a flat scraper blade 320 in a flat shape in the circumferential direction of the brush head 100 .

[0049] For example, Figure 3 As shown, in the embodiment of the present application, the scraper blade group with gaps having varying widths includes: a bent scraper blade 310 that is bent in the circumferential direction of the brush head 100, and two flat scraper blades 320 that are flat in the circumferential direction of the brush head 100, and the two flat scraper blades 320 are located on both sides of the bent scraper blade 310.

[0050] For example, Figure 4 As shown, in the embodiment of the present application, the scraper group with gaps having varying widths includes: two bent scrapers 310 in a bent shape in the circumferential direction of the brush head 100, and a flat scraper 320 in a flat shape in the circumferential direction of the brush head 100, and the two bent scrapers 310 are located on both sides of the flat scraper 320.

[0051] For example, Figure 5 As shown, in the embodiment of the present application, the set of scraper blades with gaps of varying widths includes: two curved scraper blades 310 that are both curved in the circumferential direction of the brush head 100, and the wavelengths and / or amplitudes of the waves formed by the curved scraper blades 310 are different. Figure 5 In the orientation shown, the wavelength of the wave formed by the upper curved scraper blade 310 is d1, and the wavelength of the wave formed by the lower curved scraper blade 310 is d2. If d1 and d2 are different, the gap between the two curved scraper blades 310 will change in width. In other embodiments, the amplitudes of the waves formed by the bending of the two curved scraper blades 310 can be different, and the gap between the two curved scraper blades 310 can also change in width. Similarly, in other embodiments, the amplitudes and wavelengths of the waves formed by the bending of the two curved scraper blades 310 can be different.

[0052] For example, Figure 6As shown, in the embodiment of the present application, the group of scraper blades with gaps of varying widths includes: two curved scraper blades 310 that are both curved in the circumferential direction of the brush head 100, the wavelengths of the waves formed by the two curved scraper blades 310 being the same, and the waves formed by the two curved scraper blades 310 being curved in the circumferential direction of the brush head 100 having a phase difference. Figure 6 In the orientation shown, the wavelength of the wave formed by the bending of the upper curved scraper blade 310 and the lower curved scraper blade 310 is the same. If there is no phase difference between the two curved scraper blades 310, the gap between the two curved scraper blades 310 is always the same. In the embodiment of the present application, the phase difference between the upper and lower curved scraper blades 310 (such as Figure 6 As shown in d3), the distance between the upper and lower curved scrapers 310 may vary in width.

[0053] In the embodiment of the present application, along the length direction of the brush head 100, the crests and troughs of the waves formed by the bending of the two bending scrapers 310 are opposite to each other. Figure 6 The waves formed by the two bending scrapers 310 shown have the same wavelength and a phase difference of d3, which is 1 / 2 wavelength. Therefore, the wave crest formed by the bending scraper 310 on the upper side is opposite to the wave trough formed by the bending scraper 310 on the lower side. Therefore, the gap between the two can form an alternating wide and narrow structure.

[0054] In the embodiment of the present application, the curved scraper blade 310 that is curved in the circumferential direction of the brush head 100 is wavy or folded. Figures 2 to 6 The scraper blade groups in FIG. 1 are only schematic diagrams of the local edge shapes of the scraper blade groups with gaps of varying widths. Figures 2 to 6 In each of the embodiments shown, the bent scraper 310 that is bent in the circumferential direction of the brush head 100 is generally in the shape of a broken line. However, in other embodiments, it can also be in other shapes, for example, Figure 1 , Figure 7 In addition, the curved scraper blade 310 in the embodiment of the present application, which is curved in the circumferential direction of the brush head 100, is intended to emphasize that it is not a flat surface, but rather a Figure 1 as shown in the wavy shape, or as Figures 2 to 6 The folded line shape shown, or other shapes that can create wider and narrower positions in the gap between adjacent scrapers 300.

[0055] It should be noted that the plurality of scrapers 300 included in the brush head 100 may include any single scraper set described above, such as only including Figures 2 to 6 Any one of the above, or it can include multiple scraper groups, such as including Figures 2 to 5 Any combination of two or more of .

[0056] like Figure 7 As shown, in the embodiment of the present application, taking the multiple scrapers 300 in the brush head 100 as an example, the wavelengths of the waves formed by adjacent scrapers 300 are the same, and the crests and troughs of the waves formed by adjacent scrapers 300 are opposite, that is, the gaps between any adjacent scrapers 300 in each scraper 300 have varying widths. Figure 7 In the horizontal circumferential direction in the orientation shown, each scraper blade 300 is in a continuous bending shape, that is, each scraper blade 300 is not in a planar shape. Since each scraper blade 300 is in a bending shape, the gap between two adjacent scrapers 300 has a wider position and a narrower position, wherein the wider position is as shown in FIG. Figure 7 The positions b and d shown in the figure, and the narrower positions are as follows Figure 2 Positions a, c, and e are shown in FIG.

[0057] Continue to refer to Figure 7 As shown, Figure 7 Take the scraper S1 and scraper S2 in the figure as an example, wherein the positions f and h are two troughs of scraper S1, the position g is a crest of scraper S1, the positions i and k are two crests of scraper S2, and the position j is a trough of scraper S2. The trough at the f position is opposite to the crest of the i position, and forms a narrower position L, the crest of the g position is opposite to the trough of the j position, and forms a wider position M, and the trough at the h position is opposite to the crest of the k position, and forms a narrower position N. Since each scraper blade 300 is in a continuous wave shape, and the arc spanned by a crest and a trough in each scraper blade 300 is the same, and the crests and troughs of adjacent scraper blades 300 are opposite, then the gaps between adjacent scraper blades 300 will change in width, such as Figure 7 The positions L, M, and N shown in the figure, the width of the gap changes from the position shown in L to the position shown in N. During cleaning, the scrapers 300 on the upper and lower sides of the wider position M are respectively curved crests and troughs, and the curved shape formed has a better scraping effect, and the scrapers 300 on the upper and lower sides of the wider position M can also play a guiding role. The stains scraped off at the M position will move to the narrower positions L and N on both sides under the effect of the guide, and accumulate at the narrower positions L and N, that is, the wider position can easily scrape off the stains, and the narrower position can easily accumulate the stains.

[0058] Continue to refer to Figure 7 When in use, the brush head 100 is inserted into the user's mouth, with its upper end (the end away from the brush handle 200) located inside the mouth, and the lower end (the end close to the brush handle 200) located outside the mouth. The scraper 300 on the brush head 100 contacts the tongue and can scrape off stains such as tongue coating and milk stains on the tongue. Compared with a convex or flat tongue coating brush, the bending position of the scraper 300 in this application (such as Figure 7After the tongue is in contact with the tongue, the scraper 300 in the embodiment of the present application has a larger lateral contact surface with the tongue than the tongue coating brush with convex points, and it is not easy to miss the scraping position. In addition, the scrapers 300 on both sides of the g and h positions can play a guiding role, so that the stains scraped off the M position can move to the L and N positions and accumulate. In addition, when cleaning the tongue coating, the brush head 100 can also be dipped in water first. Since the surface of the brush head 100 has multiple scrapers 300, the gaps between adjacent scrapers 300 can form a water storage or water storage area. Therefore, water is more likely to adhere to the gaps between adjacent scrapers 300. When the brush head 100 is cleaning, the water attached to the gaps can also dissolve the milk stains and rice stains on the tongue, thereby improving the cleaning effect.

[0059] like Figure 1 , Figure 7 As shown, in the embodiment of the present application, along the circumferential direction of the brush head 100, each scraper 300 is in a continuous wave shape or a continuous broken line shape. Figure 1 , Figure 7 The scraper blades 300 in the brush head 100 shown are in a continuous wave shape, that is, in the circumferential direction of the brush head 100 , the adjacent scraper blades 300 have width variations, so that in the circumferential direction of the brush head 100 , a good cleaning effect is achieved.

[0060] Figure 8 A top view of a tongue brush according to an embodiment of the present application is shown in FIG. Figure 8 As shown, in the embodiment of the present application, each scraper 300 has a long axis direction and a short axis direction in the axial projection of the brush head 100, and the long axes of the projections of each scraper 300 are located in the same plane, and the short axes of the projections of each scraper 300 are located in the same plane. Figure 8 As shown, the outer contour of each scraper 300 projected axially on the brush head 100 is not circular, but roughly an ellipse or an oblong with irregular edges, having a major axis direction and a minor axis direction. For example, in the embodiment of the present application, the minor axis of each scraper 300 projection is located on the plane where the dotted line L1 is located along the axial direction of the brush head 100, and the major axis of each scraper 300 projection is located on the plane where the dotted line L2 is located along the axial direction of the brush head 100. Each scraper 300 is formed flat as a whole and has two cleaning sides S1 and S2 with larger areas. When in use, the tongue can be quickly cleaned using the S1 side and the S2 side.

[0061] like Figure 1 , Fig. 9 As shown, in the embodiment of the present application, from the end of the brush head 100 away from the brush handle 200 to the end of the brush head 100 connected to the brush handle 200, the lengths of the major axis and minor axis of each scraper 300 in the axial projection of the brush head 100 first increase, then remain unchanged, and then decrease. Figure 1 As shown, Figure 1 This is a front view of the tongue brush. Figure 1 The left and right directions in the figure are the long axis directions of the axial projections of the scrapers 300 on the brush head. Figure 1 In the orientation shown, from top to bottom, the long axis of the projection of each scraper blade 300 first increases, then remains unchanged, and then decreases. Fig. 9 As shown, Fig. 9 This is a side view of the tongue brush. Fig. 9 The left and right directions in the figure are the short axis directions of the scrapers 300 along the axial projection of the brush head 100. Fig. 9 In the illustrated position, from top to bottom, the short axis of each scraper 300 along the axial projection of the brush head 100 first increases, then remains unchanged, and then decreases. The outer contour of the scraper 300 at the end of the brush head 100 away from the brush handle 200 is thinner overall, which is convenient for extending into the inner position of the oral cavity. The outer contour of the scraper 300 in the middle of the brush head 100 is thicker overall, which is convenient for cleaning. The outer contour of the scraper 300 at the end of the brush head 100 close to the brush handle 200 is thinner overall, which is convenient for taking the brush head 100 out of the oral cavity.

[0062] like Fig.10 As shown, on the cross section where the short axis of each scraper blade 300 is projected in the axial direction of the brush head, the edge of each scraper blade 300 is a wave crest or a wave trough. Figure 8 As shown, the plane where each short axis is located is the plane where the dotted line L1 is located along the axial direction of the brush head 100. Figure 8 In the vertical direction of the position shown, the dotted line L1 is the middle position of each scraper 300. Fig.10 The tongue coating brush is a cross-sectional view of the plane where the short axis of each scraper 300 is projected along the axial direction of the brush head. Fig.10 The edge of each scraper 300 is Figure 8 The middle position of the cleaning side S1 and the cleaning side S2 shown in the figure has the edge of each scraper 300 as a crest or a trough. According to the usual usage habits, the user will align the middle position of the cleaning side S1 or the cleaning side S2 with the tongue for cleaning. Therefore, no matter when cleaning with the cleaning side S1 or the cleaning side S2, the part in contact with the tongue is the position of the crest or the trough, so it is convenient to use according to the user's habits.

[0063] like Figure 7 As shown, in the embodiment of the present application, the connection between each scraper blade 300 and the brush head 100 is an arc surface. The connection position between the scraper blade 300 and the brush head 100 is set to an arc surface. When cleaning the brush head 100, the stains between the scrapers 300 are easily washed out by water and are not easy to accumulate at the connection between the scraper blade 300 and the brush head 100.

[0064] like Figure 7As shown, in the embodiment of the present application, the thickness of each scraper blade 300 gradually decreases from the connection with the brush head 100 along the direction of its extension to the periphery. Among them, for each scraper blade 300, its thickness is the largest at the connection position with the brush head 100, and then gradually becomes thinner along the direction of its extension to the periphery. As a result, the root of each scraper blade 300 (the connection position with the brush head 100) is thicker and the edge is thinner. The thicker root can increase the hardness of the root, making it less likely for the scraper blade 300 to fall over. The thinner edge ensures that the edge is soft and is also conducive to cleaning. Fig.10 As shown, in the embodiment of the present application, the tongue coating brush also includes a core column 400, the hardness of the core column 400 is greater than the hardness of the brush handle 200 and the brush head 100, and the core column 400 extends from the inside of the brush handle 200 to the inside of the brush head 100. Among them, the brush head 100, the scraper 300, and the brush handle 200 can be made of relatively soft materials such as silicone to avoid damage to the oral cavity during cleaning. However, if the tongue coating brush is made of silicone as a whole, it is not convenient to bear force if the overall hardness is too small, which may affect the cleaning effect. Therefore, in the embodiment of the present application, a core column 400 with a larger hardness is set in the brush handle 200 and the brush head 100, so as to support the relatively soft brush handle 200 and the brush head 100, so that the tongue coating brush has an appropriate hardness as a whole, thereby ensuring the cleaning effect of the tongue coating brush. The core column 400 can be made of plastic material or other materials with a larger hardness.

[0065] like Fig.10 As shown, in the embodiment of the present application, the end of the brush head 100 away from the brush handle 200 does not include the stem 400. The stem 400 extends from the brush handle 200 to the inside of the brush head 100 and extends a certain distance. The portion of the stem 400 extending into the brush head 100 can provide a certain support for the brush head 100, thereby improving the cleaning effect. The end of the brush head 100 away from the brush handle 200 extends to a position relatively inside the oral cavity. In order to prevent the brush head 100 from causing punctures or piercings to the oral cavity, the stem 400 is not provided at the end of the brush head 100 away from the brush handle 200, that is, the end of the brush head 100 away from the brush handle 200 is softer as a whole, thereby preventing the brush head 100 from causing punctures or piercings to the oral cavity.

[0066] like Fig. 9 , 10 As shown, in the embodiment of the present application, the end surface of the brush head 100 away from the brush handle 200 is an arc surface. Setting the end surface of the brush head 100 away from the brush handle 200 as an arc surface can prevent the end of the brush head 100 away from the brush handle 200 from causing damage to the oral cavity.

[0067] like Figure 1 As shown, in the embodiment of the present application, the diameter of the brush handle 200 first becomes thicker and then becomes thinner from one end connected to the brush head 100 to the other end. Figure 1In the illustrated position, the upper portion of the brush handle 200 is connected to the brush head 100, and the diameter of the brush handle 200 first becomes thicker and then becomes thinner from top to bottom, that is, the section where the upper portion of the brush handle 200 is connected to the brush head 100 is thinner, and it first becomes thicker and then becomes thinner during the downward extension process, that is, a shuttle-shaped section is formed. Among them, the section of the brush handle 200 close to the brush head 100 is set to be thinner, which can reduce the amount of material used and reduce costs, and the section of the brush handle 200 away from the brush head 100 is set to be shuttle-shaped, which can be convenient for users to hold.

[0068] like Figure 1 As shown, in the embodiment of the present application, the brush handle 200, the brush head 100 and each scraper 300 are integrally arranged. The brush handle 200, the brush head 100 and each scraper 300 are integrally arranged to increase the overall strength of the tongue coating brush.

[0069] In the embodiment of the present application, the multiple scrapers 300 include at least one group of adjacent scrapers 300 with gaps varying in width, that is, the gaps between adjacent scrapers 300 with gaps varying in width have wider positions and narrower positions, and the stains scraped off the tongue will be accommodated in the gaps between the scrapers 300. As the stains accumulate in the gaps between the scrapers 300, the stains will gradually fill the gaps between the scrapers 300. When the stains fill the gaps, the scrapers 300 at the narrower positions in the gaps can squeeze the stains, thereby preventing the stains from falling off the tongue brush and remaining in the user's mouth.

[0070] Finally, it should be noted that the above embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
