[0062] Specifically, Figure 1-Figure 5 , Figure 7 As shown in the figures, they are schematic diagrams of the various structures of the disposable filtering toothbrush of the present invention. It can be seen from the figures that the interior of the toothbrush body of the present invention is hollow, that is, the brush handle has a cavity, the brush head has a cavity and the two cavities are connected to form one cavity.

[0063] Among them, Figure 2-Figure 5 As shown, the brush handle is in the shape of a slender cylinder or square cylinder, and a negative pressure connector 1 with a through hole 41 is provided at the top of the brush handle so that the brush handle can be connected to a wall negative pressure barrel (not shown) and the inner cavity of the toothbrush body can be connected to the wall negative pressure barrel.

[0064] A through hole is provided on one side wall of the brush handle near the top (i.e., the negative pressure connection end) as a negative pressure hole 2 (see Figure 1-Figure 5 ), by pressing the negative pressure hole, the inner cavity of the toothbrush body is connected with the negative pressure barrel on the wall to form a passage that can generate negative pressure.

[0065] Alternatively, a negative pressure seat 10 perpendicular to the brush handle may be provided on a side wall of the brush handle near the top (see Figure 7), the center of the negative pressure seat is provided with a negative pressure hole connected to the inner cavity of the brush handle, a flexible tube connected to the outer wall of the brush handle and a plug 11 connected to the flexible tube at one end are arranged near the negative pressure seat, and the plug can be inserted into the negative pressure hole of the negative pressure seat when needed.

[0066] In addition, a through hole 42 is provided on the side wall of the brush handle opposite to the negative pressure hole, penetrating the side wall (see Figure 2-Figure 4 ), so as to input a mouthwash delivery tube which can be sealedly connected to the brush handle (such as sealed by a sealing ring, or sealed by a sealant) into the inner cavity of the toothbrush body through the hole, and the front end of the mouthwash delivery tube is open and extends into the brush head (such as the upper part of the brush head, or the lower part of the brush head), and the rear end extends out of the brush handle. The rear end of the mouthwash delivery tube is used to be connected to a mouthwash syringe, so as to inject mouthwash into the mouthwash delivery tube through the mouthwash syringe which is pre-absorbed with mouthwash, so as to deliver the mouthwash to the sponge and the soft brush through the mouthwash delivery tube.

[0067] Alternatively, a connecting pipe 47 seamlessly connected to the side wall is provided on the side wall of the brush handle opposite to the negative pressure hole (see Figure 5 ), and an isolation cavity is arranged inside the brush handle, and the top of the handle is parallel to the extension direction thereof and is connected to the inner cavity of the connecting tube as an integral whole. The front end of the isolation cavity is open and extends to the brush head (such as the upper part of the brush head, or the lower part of the brush head). The extended end of the connecting tube is used to be connected to a mouthwash syringe, so that mouthwash can be injected into the isolation cavity through the mouthwash syringe pre-sucked with mouthwash, so as to transport the mouthwash to the sponge and the soft brush through the isolation cavity.

[0068] During manufacturing, a rubber plug which can seal the opening and allow the needle of the mouthwash syringe to penetrate can be arranged at the opening at the rear end of the mouthwash delivery tube and the opening at the rear end of the connecting tube.

[0069] The brush head is in a flat square shape, and a plurality of brush holes 43 for placing soft brushes are provided on one side of the brush head. The brush holes are connected to the inner cavity of the brush head and can be circular (such as Figure 2 As shown) for arranging multiple clusters of round bristles, or in the form of long strips (as shown) Figure 3 As shown) is used to accommodate elongated bristles, and the bristles and the brush holes can be fixed in an existing manner.

[0070] A sponge hole 46 for accommodating a portion of sponge is provided on the other side of the brush head opposite to the brush hole. The sponge hole is communicated with the inner cavity of the brush head and can be square for accommodating square sponges or round for accommodating round sponges. The sponge can be fixed at the sponge hole by gluing.

[0071] A suction hole 7 connected to the inner cavity of the brush head is formed on the end surface of the brush head which is perpendicular to the side wall for accommodating the soft brush and the sponge, so that when the toothbrush body is under negative pressure conditions, the patient's oral secretions, fine sputum crusts and blood crusts can enter the toothbrush body through the suction hole and be sucked into the wall negative pressure barrel by the negative pressure.

[0072] In addition, the present invention arranges a filter outside the brush handle that is slidably connected to the brush handle, such as Figure 6 As shown, the filter comprises: a slide plate 51 with a through hole 52 in the center, the shape and size of the through hole are adapted to the shape and size of the outer shape and size of the brush handle, so that the slide plate can be mounted outside the brush handle and slide up and down along the brush handle; a pair of scrapers 53 arranged on both sides of the slide plate, which are perpendicular to the slide plate and the top ends are fixedly connected to the lower surface of the slide plate, and the scrapers are rectangular and have a length (such as Figure 6 The size of the scraper in the vertical direction is greater than or equal to the length of the brush head, the width of the scraper is greater than or equal to the width of the sponge and the soft brush, the distance between the pair of scrapers (that is, the width of the slide plate, the width of the slide plate refers to the size in the direction perpendicular to the length and width of the scraper) is less than the distance between the outermost edges of the sponge and the soft brush in the width direction of the slide plate, and the pair of scrapers and the slide plate form a scraper-type filter. When assembling, put the slide plate of the filter outside the brush handle and extend the scraper toward the brush head.

[0073] Furthermore, in order to guide the filter in the direction of up and down movement of the brush handle and prevent it from excessively shaking relative to the brush handle, the through hole of the slide plate and the outer wall of the brush handle can be connected together by a key connection, such as providing a ridge on the inner wall of the through hole of the slide plate and providing a groove matching the ridge on the outer wall of the brush handle (not shown in the figure), or providing a groove on the inner wall of the through hole of the slide plate and providing a ridge matching the groove on the outer wall of the brush handle.

[0074] Below, taking a disposable filter toothbrush with a mouthwash delivery tube as an example, its use process is briefly described:

[0075] Before use, suck the mouthwash water to be used into a mouthwash syringe that meets the preset volume requirements (such as a 10ml syringe), connect the needle of the syringe to the rear end of the mouthwash delivery tube, push the syringe to inject the mouthwash into the mouthwash delivery tube until the mouthwash flowing out of the front end of the mouthwash delivery tube completely wets the soft brush and sponge, and then connect the negative pressure connector to the wall negative pressure barrel.

[0076] After the negative pressure connector is connected to the negative pressure barrel on the wall, use a toothbrush to clean the patient's mouth. When cleaning, use the soft brush on one side to remove the patient's tongue coating and stubborn residues in the mouth, especially the soft brush can be used to clean the patient's teeth. Use the sponge on the other side to clean the patient's hard palate, tongue surface and cheeks on both sides. During the cleaning process, you can inject mouthwash as needed.

[0077] During oral cleaning, if the soft brush or sponge is too wet or there is too much saliva and sputum in the patient's mouth, the user can use the thumb to touch the negative pressure hole to adjust the negative pressure attraction in the passage formed by the wall negative pressure barrel and the inner cavity of the toothbrush body, so as to absorb the excess liquid (such as excessive mouthwash absorbed by the soft brush or sponge and saliva and sputum secreted by the patient's mouth) through the suction hole, thereby preventing the patient from accidentally inhaling these liquids and causing lung infection. If there are foreign objects attached to the soft brush or sponge that cannot be sucked away through the suction hole, such as large pieces of sputum scabs, blood scabs, excessive secretions, etc., the filter can be pushed up and down along the brush handle so that the pair of scrapers of the filter squeeze the soft brush or sponge respectively, thereby scraping off the foreign objects.

[0078] The negative pressure hole is pressed by fingers to control the negative pressure only when the soft brush or sponge needs to be rinsed during use, and the mouthwash in the syringe enters the sponge and the soft brush end to quickly rinse them. The multifunctional brush of the present invention is a disposable item and is discarded after use.

[0079] Compared with the prior art which is unable to clean the interdental spaces of patients who vomit a lot of blood, thereby causing blood scabs to remain in the patient's mouth for a long time, the disposable filtering toothbrush of the present invention can be used to clean the interdental spaces of patients with a soft-bristle brush, and the sponge can clean sensitive areas such as the patient's hard palate, tongue surface and cheeks on both sides. The suction hole can attract excess saliva and fine residues in the patient's mouth, and the mouthwash injected by the syringe can timely clean the soft-bristle brush or sponge on the brush head and quickly clean the patient's mouth, thereby ensuring that blood scabs and foreign objects in the patient's mouth are cleaned in time and improving the patient's comfort. The filter can remove large pieces of sputum scabs, blood scabs, etc. that cannot be cleaned and adhere to the soft-bristle brush or sponge, thereby increasing the single use time of the toothbrush of the present invention. Compared with the prior art toothbrush which cannot be used anymore after the top is contaminated, the toothbrush of the present invention can reduce the cost burden of replacing toothbrushes for patients and also reduce the nursing workload of medical staff.

[0080] Although the present invention has been described in detail above, the present invention is not limited thereto. Those skilled in the art may make modifications based on the principles of the present invention. Therefore, all modifications made based on the principles of the present invention should be understood to fall within the protection scope of the present invention.
