Patent Description:
During the process of feeding infants, liquid food can be fed using baby utensils such as bottles. However, as infants grow, the infants need to supplement various nutrients and exercise their eating skills. When selecting solid foods such as fruits, vegetables, or meats, infants with weak self-control can easily swallow these food without chewing, which can lead to choking, posing a significant risk to their health. Therefore, chewing devices to aid infant feeding are widely used.

Existing chewing devices generally include an upper body part, a lower body part, and a silica gel net. The upper body part is typically made of plastic, and the lower body part is equipped with a fastener on one or both sides. After food is placed into the silica gel net, the silica gel net passes through a mounting position of the lower body part, and then the upper and lower body parts are assembled and fixed together with the fastener. Such a chewing device is known from <CIT>.

The related art has the following defects: During use, if the infant inserts the chewing device too deeply into their mouth, leading to unreasonable use (biting beyond the acceptable range), the upper body part can easily separate from the lower body part and the silica gel net under the force of biting and pulling. At this point, the lower body part loses its fixing function, and the silica gel net can easily separate from the lower body part. If the silica gel net is small, there is a substantial risk that the infant may accidentally swallow the silica gel net.

An embodiment of the present application provides an infant food chewing device. The infant food chewing device is stable in structure and a silica gel net is not prone to falling off.

The present application uses the solutions below.

An infant food chewing device is provided. The device includes a net bag, a cover, and a fixing hoop. The net bag includes a bag body. The bag body has a receiving cavity. A cavity wall of the receiving cavity is provided with several through holes for food to pass through. A first fixing ring extends from one side of an open end of the bag body facing away from the center of the open end. The cover includes a cover body having a mounting side surface. An enclosing wall and a blocking block are disposed on the mounting side surface. The blocking block is located in an annular area of the enclosing wall. The blocking block and the enclosing wall are spaced apart. The blocking block has a blocking side face abutting an end face of the open end and blocking the open end. The fixing hoop is sleeved on the outer periphery of the blocking block and the first fixing ring. The fixing hoop is detachably connected to the blocking block and the first fixing ring. The enclosing wall at least partially shields the outer side surface of the fixing hoop.

In an optional solution of the infant food chewing device, the outer side surface of the fixing hoop includes an outer peripheral side face and a first transition arc face connected to the outer peripheral side face. The first transition arc face is a convex arc face. The outer peripheral side face and the first transition arc face are disposed in an axial direction of the fixing hoop. The first transition arc face is disposed on one side of the outer peripheral side face close to the net bag. The enclosing wall shields at least the outer peripheral side face.

In an optional solution of the infant food chewing device, the enclosing wall shields a portion of the first transition arc face.

In an optional solution of the infant food chewing device, the blocking side face is provided with a fitting portion. The fitting portion is inserted in the open end. An end face of the enclosing wall protrudes from the blocking side face.

In an optional solution of the infant food chewing device, the thickness of the enclosing wall gradually reduces in a direction from the cover to the net bag.

In an optional solution of the infant food chewing device, one side surface of the enclosing wall facing away from the fixing hoop is an inclined surface.

In an optional solution of the infant food chewing device, an included angle between the inclined surface and one side surface of the enclosing wall facing the blocking block is θ. <NUM>° ≤ θ ≤ <NUM>°.

In an optional solution of the infant food chewing device, θ = <NUM>°.

In an optional solution of the infant food chewing device, an end face of the enclosing wall is a second transition arc face. The second transition arc face is a convex arc face.

In an optional solution of the infant food chewing device, the device includes a dust cover. A first buckle member is disposed on one side surface of the enclosing wall facing away from the blocking block. A second buckle member is disposed on the inner wall of the dust cover. The first buckle member and the second buckle member are buckled. The net bag and the fixing hoop are located inside the dust cover.

The present application has the beneficial effects below. The fixing hoop connects and fixes the net bag and the cover, improving the connection strength between the cover and the net bag, and reducing the probability of the net bag detaching during use. The enclosing wall is disposed on the cover and shields a portion of the fixing hoop. If the infant excessively pushes the net bag into the mouth and the biting range extends to an area near the fixing hoop, the infant's direct biting area on the fixing hoop becomes relatively small under the shielding of the enclosing wall. More biting force is applied directly to the enclosing wall of the cover. That is, the effective biting area on the fixing hoop is minimized to prevent the infant from pulling off the fixing hoop from the food chewing device during use, ensuring the connection stability between the net bag and the cover, and avoiding a scenario where the infant might swallow the net bag mistakenly due to the net bag falling off.

The present application is further described below in detail in conjunction with drawings and embodiments.

To make solved problems, adopted solutions and achieved effects of the present application clearer, the solutions in the embodiments of the present application are further described in detail in conjunction with the drawings. Apparently, the embodiments described below are part, not all, of the embodiments of the present application. Based on the embodiments described herein, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of the present application.

In the description of the present application, unless otherwise expressly specified and limited, the term "connected to each other", "connected" or "secured" is to be construed in a broad sense, for example, as securely connected, detachably connected or integrated; mechanically connected or electrically connected; directly connected to each other or indirectly connected to each other via an intermediary; or internally connected between two elements or interaction relations between two elements. For those of ordinary skill in the art, specific meanings of the preceding terms in the present application may be understood based on specific situations.

As shown in <FIG>, the present application provides an infant food chewing device including a net bag <NUM>, a cover <NUM>, and a fixing hoop <NUM>. The net bag <NUM> includes a bag body <NUM> having a receiving cavity <NUM>. A cavity wall of the receiving cavity <NUM> is provided with several through holes <NUM> for food to pass through. A first fixing ring <NUM> extends from one side of an open end of the bag body <NUM> facing away from the center of an open end. The cover <NUM> includes a cover body having a mounting side surface. An enclosing wall <NUM> and a blocking block <NUM> are disposed on the mounting side surface. The blocking block <NUM> is disposed in an annular area of the enclosing wall <NUM>. The blocking block <NUM> and the enclosing wall <NUM> are spaced apart. The blocking block <NUM> has a blocking side face <NUM> abutting an end face of the open end and blocking the open end. The fixing hoop <NUM> is sleeved on the outer periphery of the blocking block <NUM> and the first fixing ring <NUM>. The fixing hoop <NUM> is detachably connected to both the blocking block <NUM> and the first fixing ring <NUM>. The enclosing wall <NUM> at least partially shields the outer side surface of the fixing hoop <NUM>. The fixing hoop <NUM> connects and fixes the net bag <NUM> and the cover <NUM>, improving the connection strength between the cover <NUM> and the net bag <NUM>, and reducing the probability that the net bag <NUM> falls off during use. The enclosing wall <NUM> is disposed on the cover <NUM>. The enclosing wall <NUM> shields a portion of the fixing hoop <NUM>. If the infant excessively pushes the net bag <NUM> into the mouth and the biting range extends to an area near the fixing hoop <NUM>, the infant's direct biting area on the fixing hoop <NUM> becomes relatively small under the shielding of the enclosing wall <NUM>. More biting force is applied directly to the enclosing wall <NUM> of the cover <NUM>. That is, the effective biting area on the fixing hoop <NUM> is minimized to prevent the infant from pulling off the fixing hoop <NUM> from the food chewing device during use, ensuring the connection stability between the net bag <NUM> and the cover <NUM>, and avoiding a scenario where the infant might swallow the net bag <NUM> mistakenly due to the net bag <NUM> falling off.

In this embodiment, the first fixing ring <NUM> is provided with a first clamping groove <NUM>. A peripheral portion of the blocking block <NUM> is provided with a second clamping groove <NUM>. Mounting holes <NUM> are formed on and extended through the fixing hoop <NUM>. An open end of the net bag <NUM> and one end of the blocking block <NUM> provided with the blocking side face <NUM> are inserted in the mounting hole <NUM> from two ends of the mounting hole <NUM>, respectively. A second fixing ring <NUM> extends from one end of the fixing hoop <NUM> close to the net bag <NUM> and facing the center of the mounting hole <NUM>. The second fixing ring <NUM> abuts the first fixing ring <NUM>. A first clamping block <NUM> connected to the first clamping groove <NUM> is disposed on the second fixing ring <NUM>. A second clamping block <NUM> connected to the second clamping groove <NUM> is disposed on a hole wall of the mounting hole <NUM>. That is, the fixing hoop <NUM> is clamped to the blocking block <NUM> and the first fixing ring <NUM> separately.

Further, the outer side surface of the fixing hoop <NUM> includes an outer peripheral side face <NUM> and a first transition arc face <NUM> connected to the outer peripheral side face <NUM>. The first transition arc face <NUM> is a convex arc face. The outer peripheral side face <NUM> is connected to an end face of one end of the second fixing ring <NUM> facing away from the cover <NUM> through the first transition arc face <NUM>. The enclosing wall <NUM> shields at least the outer peripheral side face <NUM>. In this embodiment, in a use state, the second fixing ring <NUM> is disposed at one end of the fixing hoop <NUM> close to the infant. The first transition arc face <NUM> is disposed between the outer peripheral side face <NUM> of the fixing hoop <NUM> and the second fixing ring <NUM> so that the outer surface of the fixing hoop <NUM> is smooth, avoiding the fixing hoop <NUM> from scratching the skin of the infant. It is to be understood that, in a use state, the outer peripheral side face <NUM> is perpendicular to the face of the infant. The enclosing wall <NUM> shields at least the outer peripheral side face <NUM>, avoiding the infant from directly biting on the outer peripheral side face <NUM> of the fixing hoop <NUM>, thereby reducing the effective biting area on the fixing hoop <NUM>, and avoiding the fixing hoop <NUM> from falling off. Due to the particularity of the arc-shaped structure of the first transition arc face <NUM>, a "slip" phenomenon occurs when the infant bites the first transition arc face <NUM>, avoiding the fixing hoop <NUM> from being pulled off.

Optionally, the enclosing wall <NUM> shields a portion of the first transition arc face <NUM>. The enclosing wall <NUM> shields a portion of the first transition arc face <NUM>, ensuring that the enclosing wall <NUM> completely shields the outer peripheral side face <NUM> of the fixing hoop <NUM>, thereby providing a certain precision error for the machining of the enclosing wall <NUM>, and reducing the manufacturing difficulty and the manufacturing cost.

Specifically, the blocking side face <NUM> is provided with a fitting portion <NUM>. The fitting portion <NUM> is inserted in the open end. An end face of the enclosing wall <NUM> protrudes from the blocking side face <NUM>. The fitting portion <NUM> can increase the contact area between the net bag <NUM> and the cover <NUM>. The end face of the enclosing wall <NUM> protrudes from the blocking side face <NUM> so that the infant excessively pushes the net bag <NUM> into the mouth and the biting range extends to an area near the enclosing wall <NUM>, the enclosing wall <NUM> abuts the fixing hoop <NUM> under the action of a biting force, making the fixing hoop <NUM> and the fitting portion <NUM> together clamp the net bag <NUM>, and increasing the friction force between the net bag <NUM>, the cover <NUM>, and the fixing hoop <NUM>, thereby preventing the fixing hoop <NUM> and the net bag <NUM> from being pulled off. In this embodiment, the fitting portion <NUM> has an interference fit with the net bag <NUM> so that the connection stability between the cover <NUM> and the net bag <NUM> can be improved. In this embodiment, the diameter of the blocking block <NUM> is <NUM>. The diameter of the fitting portion <NUM> is <NUM>. The blocking block <NUM> and the fitting portion <NUM> are coaxially disposed. The height of the fitting portion <NUM> is <NUM>. The overall height of the fixing hoop <NUM> is <NUM>. The height of the outer peripheral side face <NUM> of the fixing hoop <NUM> is <NUM>.

Further, the thickness of the enclosing wall <NUM> gradually reduces in the direction from the cover <NUM> to the net bag <NUM>. The thickness of the surrounding wall <NUM> gradually reduces, improving the appearance of the infant food chewing device, and making the infant food chewing device full of aesthetic feeling.

Further, one side surface of the enclosing wall <NUM> facing away from the fixing hoop <NUM> is an inclined surface <NUM>. One side surface of the enclosing wall <NUM> facing away from the fixing hoop <NUM> is the inclined surface <NUM> so that the enclosing wall <NUM> can be smoothly connected to the first transition arc face <NUM> of the fixing hoop <NUM>, thereby improving the infant use experience. Of course, one side surface of the enclosing wall <NUM> facing away from the fixing hoop <NUM> is not limited to the inclined surface <NUM>, and may be a convex arc face.

Optionally, an included angle θ between the inclined surface <NUM> and one side surface of the enclosing wall <NUM> facing the blocking block <NUM> is θ. <NUM>° ≤ θ ≤ <NUM>°. The range of θ is between <NUM>° and <NUM>°, ensuring the thickness of the connection position between the enclosing wall <NUM> and the blocking block <NUM>, thereby ensuring the connection strength between the enclosing wall <NUM> and the blocking block <NUM>.

Optionally, θ = <NUM>°. In this way, the appearance and the thickness of the enclosing wall <NUM> can be taken into account as much as possible to ensure the connection stability between the enclosing wall <NUM> and the blocking block <NUM>. In other optional embodiments, θ may also be <NUM>°, <NUM>°, <NUM>°, <NUM>°, <NUM>°, <NUM>°, <NUM>°, <NUM>°, <NUM>°, <NUM>°, and <NUM>°.

Optionally, the end face of the enclosing wall <NUM> is a second transition arc face <NUM>. The second transition arc face <NUM> is a convex arc face. The end face of the enclosing wall <NUM> is the convex second transition arc face <NUM>. The second transition arc face <NUM> can smoothly connect the inclined surface <NUM> of the enclosing wall <NUM> to the inner side of the enclosing wall <NUM> (i.e. a side surface of the enclosing wall <NUM> facing the blocking block <NUM>), avoiding the angular structure of the enclosing wall <NUM>, thereby avoiding the enclosing wall <NUM> from scratching the skin of the infant during the use. In this embodiment, the enclosing wall <NUM> and the blocking block <NUM> are integrally formed so that the height of the enclosing wall <NUM> is <NUM>. The height is set so that the enclosing wall <NUM> can cover the first transition arc face <NUM> of the fixing hoop <NUM> after the cover <NUM> and the fixing hoop <NUM> are combined, and the biting range (area) of the fixing hoop <NUM> is shielded.

Referring to <FIG>, optionally, the infant food chewing device includes a dust cover <NUM>. A first buckle member <NUM> is disposed on one side surface of the enclosing wall <NUM> facing away from the fixing hoop <NUM>. A second buckle member <NUM> is disposed on the inner wall of the dust cover <NUM>. The first buckle member <NUM> and the second buckle member <NUM> are buckled. The net bag <NUM> and the fixing hoop <NUM> are located inside the dust cover <NUM>. In this embodiment, the first buckle member <NUM> is a one ring-shaped groove structure provided on the outer surface of the enclosing wall <NUM>. The second buckle member <NUM> is a one ring-shaped convex provided on the inner surface of the dust cover <NUM>. The second buckle member <NUM> is inserted in the first buckle member <NUM> to achieve the cover of the dust cover <NUM> and the cover <NUM>. The dust cover <NUM> can cover the cover body <NUM> in a non-use state, avoiding the net bag <NUM> from being exposed, thereby avoiding contaminating the net bag <NUM>. In this embodiment, the dust cover <NUM> is U-shaped as a whole, <NUM> high and hollow inside. The effective depth of the dust cover <NUM> is <NUM>. The dust cover <NUM> can be used for placing food and provided with scale lines. An upper end portion of the dust cover <NUM> is in the shape whose the outer edge tapers with the maximum diameter of <NUM> and the minimum diameter of <NUM>. The shape is viewed as a bowl, and the bowl-shaped portion is <NUM> in height. The part with the maximum diameter is set as an opening. The first buckle member <NUM> has a groove width of <NUM> and a depth of <NUM>. The size of the second buckle member <NUM> corresponds to the size of the first buckle member <NUM>.

Further, in this embodiment, the first clamping groove <NUM> is an annular clamping groove. The first clamping block <NUM> is an annular projection. The first clamping block <NUM> is inserted in the first clamping groove <NUM> to be clamped. The second clamping groove <NUM> is an annular clamping groove. The second clamping block <NUM> is an annular projection. The second clamping block <NUM> is inserted in the second clamping groove <NUM> to be clamped. The groove direction of the second clamping groove <NUM> and the groove direction of the first clamping groove <NUM> are disposed at an included angle. Optionally, the groove direction of the first clamping groove <NUM> is perpendicular to the groove direction of the second clamping groove <NUM>. One clamping groove is provided on the net bag <NUM>. One clamping groove is provided on the net bag <NUM>. The groove directions of the two clamping grooves are disposed at an included angle. Corresponding to each clamping groove, the fixing hoop <NUM> is provided with one annular clamping block, forming a double clamping structure. The double clamping structure forms a mutual clamping force, increasing the connection strength of the net bag <NUM>, the cover <NUM> and the fixing hoop <NUM> after assembly, and effectively preventing the net bag <NUM> from being separated from the fixing hoop <NUM>. Moreover, the double clamping structure can also form a double seal, effectively increasing the sealing effect between the cover <NUM> and the net bag <NUM>, preventing the food juice in the net bag <NUM> from flowing out from the joint position of the net bag <NUM> and the cover <NUM>. In this embodiment, the second clamping groove <NUM> has a groove width of <NUM> and a depth of <NUM>. The size of the second clamping block <NUM> corresponds to the size of the second clamping groove <NUM>. The first fixing ring <NUM> has a diameter of <NUM> and a thickness of <NUM>. The first clamping groove <NUM> has a groove width of <NUM> and a depth of <NUM>. The size of the first clamping block <NUM> corresponds to the size of the first clamping groove <NUM>. The open end of the bag body <NUM> has an aperture of <NUM> and is rounded.

In this embodiment, the net bag <NUM>, the cover <NUM> and the fixing hoop <NUM> are all made of silica gel. This design enables the whole infant food chewing device to have a more comfortable hand feel and taste, avoiding contact of hard plastic or metal materials with the mouth and hands of the infant, and reducing the resistance of the infant during use. The diameter of each through hole <NUM> on the net bag <NUM> is <NUM>. The food juice flows out from the net bag <NUM> to filter and isolate food residues. The capacity of the net bag <NUM> may be set in large, medium and small sizes and designed according to different loads.
