[0033] See Figures 1 to 7 In the specific embodiment shown, the present utility model discloses a squeezing type bidet, comprising: a squeezing bottle body 10 and an extension rod 20. The inside of the squeezing bottle body 10 is a cavity. The extension rod 20 is telescopically connected to the squeezing bottle body 10. The extension rod 20 is a hollow structure, and a liquid outlet member 30 is provided on one side of the top end of the extension rod 20. The extension rod 20 communicates with the cavity. When the extension rod 20 and the squeezing bottle body 10 are in a first connection state, that is, the squeezing type bidet is in a use state; when the extension rod 20 and the squeezing bottle body 10 are in a second connection state, that is, the squeezing type bidet is in a storage state.

[0034] Specifically, the interior of the extrusion bottle body 10 is a cavity. The extension rod 20 is telescopically connected to the extrusion bottle body 10. The extension rod 20 is a hollow structure, and a liquid outlet member 30 is provided on one side of the top end of the extension rod 20. The extension rod 20 communicates with the cavity. When the extension rod 20 and the extrusion bottle body 10 are in the first connection state, that is, the extrusion type body washer is in the use state. When the extension rod 20 and the extrusion bottle body 10 are in the second connection state, that is, the extrusion type body washer is in the storage state, that is, the extension rod 20 can be retracted into the extrusion bottle body 10, so as to reduce the occupied space of the entire body washer and facilitate storage, thus facilitating storage and carrying, and is very suitable for scenarios such as traveling. In addition, since the extension rod 20 is a hollow structure and communicates with the cavity of the extrusion bottle body 10, when the extrusion bottle body 10 is squeezed, the liquid in the bottle can smoothly pass through the extension rod 20 and be ejected along the liquid outlet member 30 for cleaning. This design reduces the risk of liquid overflow, and at the same time is convenient for cleaning and maintenance, helping to maintain the hygiene of the body washer. In addition, the use and storage conversion of the body washer can be realized through simple telescopic operation, without complex installation or disassembly process, greatly improving the user experience.

[0035] In one embodiment, a beveled surface is provided on one side of the top end of the extension rod 20. A liquid outlet is provided on the beveled surface. A sealing sleeve 40 is provided at the liquid outlet. The liquid outlet member 30 is installed on the sealing sleeve 40.

[0036] Specifically, the design of the beveled surface enables the liquid outlet to be aligned with the cleaning area at a more reasonable angle, so as to ensure that the liquid can be more accurately sprayed onto the part to be cleaned, avoiding problems such as liquid splashing or incomplete cleaning caused by improper angles. This design helps to improve the cleaning effect, enabling users to clean the private parts or areas that require special attention more thoroughly. In addition, through the design of the beveled surface, users can more flexibly respond to different cleaning needs. For example, when cleaning hard-to-reach corners or gaps, the beveled surface design can provide a more suitable spraying angle, making the cleaning process smoother and more efficient. In addition, since the beveled surface design makes the cleaning angle more reasonable, users do not need to frequently adjust the position or angle of the body washer to achieve effective cleaning, thus simplifying the operation process and improving the use efficiency. In addition, the sealing sleeve 40 provided at the liquid outlet not only plays a role in fixing the liquid outlet member 30, but also ensures the sealing performance of the liquid outlet in the non-use state, which helps to prevent liquid leakage or bacterial intrusion, ensuring the hygiene and safety of the body washer. The detachable design of the sealing sleeve 40 and the liquid outlet member 30 enables users to conveniently carry out cleaning and maintenance work, further improving the hygiene performance and service life of the body washer.

[0037] In one embodiment, the liquid outlet member 30 is provided with an inner ring hole 31, a middle ring hole 32 and an outer ring hole 33; the inner ring hole 31 has the largest aperture, the hole wall of the middle ring hole 32 is inclined, and the outer ring hole 33 has the smallest aperture.

[0038] Specifically, the inner ring hole 31 has the largest aperture (for example, 0.12 - 0.2 mm), which results in a relatively thick water column when water flows out, and a relatively large water flow force. This design is suitable for areas that require a strong impact force for cleaning, such as stubborn dirt or hard-to-clean gaps. Moreover, the thick water column can generate a large impact force to help quickly remove dirt and residues on the surface and improve the cleaning efficiency. Additionally, the hole wall of the middle ring hole 32 (for example, 0.06 - 0.1 mm) is inclined. This design causes the water flow to form an intersection point (i.e., focus) when water flows out, that is, the water flows intersect at a specific point and generate a certain impact force. The formation of the intersection point helps to concentrate the force of the water flow and conduct targeted flushing on the skin, which is particularly suitable for areas that need to be cleaned intensively, such as hard-to-reach parts like folds and depressions. Although it has a certain impact force, due to the concentration of the water flow and the formation of the intersection point, the water flow of the middle ring hole 32 can maintain a certain degree of comfort when flushing the skin and avoid causing excessive irritation to the skin. Additionally, the outer ring hole 33 has the smallest aperture (for example, 0.02 - 0.05 mm), and the water flow is thin, soft and sweeps across the skin when water flows out. This design is suitable for areas that require gentle cleaning, such as sensitive skin or delicate parts. The thin and soft water flow can gently slide across the skin surface to help remove fine dirt and grease, while reducing friction and irritation to the skin, and has a certain skin care effect.

[0039] In one embodiment, the lower end of the extension rod 20 is connected with a mounting sleeve 50. The mounting sleeve 50 is movably connected to the extrusion bottle body 10. A raised position 51 is provided on the outer side of the mounting sleeve 50, and the extrusion bottle body 10 is provided with an annular card slot corresponding to the raised position 51, so that the extension rod 20 and the extrusion bottle body 10 are in a first connection state.

[0040] Specifically, the extension rod 20 is telescopically connected to the extrusion bottle body 10 through the mounting sleeve 50. This design enables the extension rod 20 to move up and down relative to the extrusion bottle body 10, facilitating the telescoping of the extension rod 20. Additionally, the raised position 51 on the outer side of the mounting sleeve 50 matches the annular card slot on the extrusion bottle body 10. When the extension rod 20 is pulled up to the highest position, the raised position 51 will snap into the annular card slot. This cooperation not only serves as a positioning function to ensure that the extension rod 20 does not slide randomly but also enhances the connection stability. Moreover, the tight fit between the raised position 51 and the annular card slot also serves as a sealing function. During the use of the bidet, this sealing design can effectively prevent liquid from leaking at the connection, ensuring the normal use of the bidet and the user experience. Additionally, when the user pulls up the extension rod 20 to the highest position, the cooperation between the raised position 51 and the annular card slot will generate a certain sense of tactile jerk. This design can intuitively prompt the user that the extension rod 20 has reached the highest position and there is no need to continue pulling forcefully, thereby enhancing the user experience. Additionally, the height adjustment and positioning of the extension rod 20 can be achieved through a simple pulling action, which is convenient and intuitive to operate. This design conforms to the ergonomic principle and reduces the operation difficulty and complexity for the user when using the bidet.

[0041] In one embodiment, a circular groove 21 is provided at the lower end of the extension rod 20, and the mounting sleeve 50 is provided with an annular clamping portion 52 corresponding to the circular groove 21.

[0042] Specifically, the cooperation between the circular groove 21 and the annular clamping portion 52 provides an accurate positioning point for the connection between the extension rod 20 and the mounting sleeve 50. This design ensures the stability of the extension rod 20 in the mounting sleeve 50 and prevents loosening or deviation caused by external forces during use. Additionally, through the clamping of the circular groove 21 and the annular clamping portion 52, the connection between the extension rod 20 and the mounting sleeve 50 is more secure, enhancing the structural strength of the entire bidet, which helps to improve the durability and service life of the bidet. Moreover, the tight fit between the circular groove 21 and the annular clamping portion 52 helps to form a sealing barrier to prevent liquid from leaking at the connection between the extension rod 20 and the mounting sleeve 50, which is crucial for maintaining the cleanliness and hygiene of the bidet and also avoids user discomfort or product damage caused by leakage.

[0043] In one embodiment, an annular connecting end 53 extends inwardly from the bottom of the mounting sleeve 50, and the bottom of the extension rod 20 abuts against the annular connecting end 53.

[0044] Specifically, the annular connection end 53 provides a stable support surface for the extension rod 20, enabling the extension rod 20 to remain stable when moving up and down or under external forces, and not being prone to shaking or deviation. This stable support helps to improve the overall stability and reliability of the bidet. Additionally, through the abutment of the bottom of the extension rod 20 against the annular connection end 53, precise positioning of the extension rod 20 in the mounting sleeve 50 is achieved. This positioning method helps to ensure that the extension rod 20 always remains in the correct position during use, thus meeting the cleaning needs of users. Moreover, when the extension rod 20 is subjected to external forces (such as the pressure applied by the user), the annular connection end 53 can disperse the pressure to the bottom of the mounting sleeve 50, thereby reducing the impact and damage to the extension rod 20 itself or the connection, and this pressure dispersion mechanism helps to extend the service life of the bidet.

[0045] In one embodiment, a filter sheet 60 is placed on the annular connection end 53, and the bottom of the extension rod 20 abuts against the filter sheet 60.

[0046] Specifically, the main function of the filter sheet 60 is to filter out small particles, debris, sediment, etc. in the water flow. If these impurities are not filtered out, they may affect the user experience during use and even pose a potential threat to health. Through the filtering function of the filter sheet 60, it can ensure that the water flow entering the extension rod 20 is cleaner, thereby enhancing the user's cleaning experience. Additionally, when the bidet is used for a long time, if there are a large number of impurities in the bottle body, it may cause blockage of the internal pipeline or the liquid outlet part 30 of the extension rod 20. The presence of the filter sheet 60 can effectively reduce this risk of blockage, protect the normal operation of the bidet, extend the service life of the product, and filtering out impurities in the water not only improves the cleanliness of the water used but also reduces the risk of skin irritation or infection caused by impurities, thereby protecting the health of the user. Moreover, the filter sheet 60 is usually detachable and replaceable, which enables the user to replace the filter sheet 60 regularly according to needs to maintain the good performance of the product and the cleanliness of the water used. This easy-to-maintain design also increases the user's satisfaction with the product.

[0047] In one embodiment, a rod cap part 70 is provided at the top of the extension rod 20, and a sealing ring 80 is provided between the rod cap part 70 and the extension rod 20.

[0048] Specifically, the setting of the rod cap 70 enables the bidet to be in a storage state. When the rod cap 70 is lifted, the extension rod 20 can be extended to convert to the use state. The main function of the sealing ring 80 is to form a tight sealing layer between the rod cap 70 and the extension rod 20, preventing water or other liquids from leaking from the connection. This is crucial for maintaining the cleanliness and hygiene of the bidet, avoiding user discomfort or product damage caused by leakage. Additionally, the improved sealing effect also means that during use, users can use the product with more peace of mind, without worrying about potential safety hazards caused by leakage. Moreover, the presence of the sealing ring 80 not only serves a sealing purpose but also enhances the connection strength between the rod cap 70 and the extension rod 20 through its elasticity and compressibility. This enhanced connection makes the product more stable during use and reduces the risk of failure caused by loose connections.

[0049] In one embodiment, the extrusion bottle body 10 includes a bottle body 11 and a bottle cap 12. The bottle cap 12 is threadedly connected to the bottle body 11. The mounting sleeve 50 is movably connected to the bottle cap 12, and the annular card slot is provided on the bottle cap 12.

[0050] Specifically, the bottle cap 12 is threadedly connected to the bottle body 11. This connection method has strong stability and sealing performance. The threaded structure enables the bottle cap 12 to be tightly screwed onto the bottle body 11, preventing liquid leakage. At the same time, it is also convenient for users to easily open or close the bottle cap 12 as needed. Additionally, the mounting sleeve 50 is movably connected to the bottle cap 12. This design allows the mounting sleeve 50 to move up and down along the bottle cap 12 to switch the state of the bidet.

[0051] In one embodiment, a sealing ring 90 is further provided on the outer side of the top end of the extension rod 20. The sealing ring 90 cooperates with the inner wall of the bottle cap 12 to enable the extension rod 20 and the extrusion bottle body 10 to be in a second connection state.

[0052] Specifically, through the cooperation of the sealing ring 90 and the inner wall of the bottle cap 12, the extension rod 20 can be smoothly received into the extrusion bottle body 10, thus reducing the overall occupied space, which is particularly important for users who need to carry the product, such as in scenarios like traveling. The user can simply push the extension rod 20 into the extrusion bottle body 10 to complete the storage operation. This design simplifies the operation steps and improves the user-friendliness. Additionally, in the stored state, the sealing ring 90 and the bottle cap 12 together provide a good protective barrier for the extension rod 20, which helps prevent damage or deformation of the extension rod 20 caused by external impacts or collisions during carrying or storage. Moreover, the design of the sealing ring 90 ensures that when the extension rod 20 is received into the extrusion bottle body 10, a tight sealing connection is formed between it and the inner wall of the bottle cap 12, improving the sealing performance and helping prevent external dust, dirt and other impurities from entering the bottle, maintaining the cleanliness and hygiene of the bottle interior.

[0053] This extrusion-type douche can be used in fields such as vaginal irrigation. By filling the bottle body 11 with liquid, tightening the bottle cap 12, then pulling out the extension rod 20, slowly inserting the extension rod 20 into the vagina, and finally squeezing the bottle body 11 to eject the liquid from the liquid outlet member 30, the cleaning can be achieved.

[0054] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
